cirq - v1.6.0

Cirq v1.6.0 release

Summary

Removed the Cirq-Rigetti package. Increased the minimum Python version to 3.11. Enhanced support for experiment types and circuits for Quantum Engine. Added a new Quantum Virtual Machine "willow_pink", to simulate state-of-art Google processors.

Removal of cirq-rigetti

The Cirq-Rigetti subpackage has been removed after its deprecation in #7058. For legacy code needs, please use the last release cirq-rigetti-1.5.0.

General code maintenance

Increased type-check coverage by adding type annotations to unit tests (an ongoing effort). Updated annotations syntax to confirm to PEP-585. Activated ruff tool for fast code checking and linting. Deleted the outdated maintenance tool pr_monitor and eliminated the use of Docker in tools and tests.

cirq-core

Added CXSWAP and CZSWAP gates. Added transformers for manipulating operation tags and for parameterizing tagged operations. Added support for parameterized circuits in the merge-single-qubit-gates transformer. Added a new implementation of parallel XEB accepting circuits instead of single gates. Improved Randomized Benchmarking to reduce the size of generated circuits. Simplified decomposition of controlled gates with global phase. Added JSON serialization support for NoiseModel classes. Extended the QASM import parser to understand more OpenQASM 2.0 gates. Improved the output and speed of Quantum Shannon Decomposition. Implemented support for adding tags to Cirq moments. Enhanced apply_unitary and unitary to accept numpy matrices.

API change

Changed CircuitOperation to assume use_repetition_ids=False by default (you can pass the explicit argument use_repetition_ids=True to restore the previous behavior).

cirq-google

Added specifications for the new Quantum Virtual Machine (QVM) "willowpink" with updated demos in QVM notebooks. Improved serialization of Cirq objects for Quantum Engine (QE) for better performance and to support more Cirq types. Added classes to express analog qubit frequency and coupling experiments at QE. Deprecated hard-coded default gate times in `noisepropertiesfromcalibration`.

cirq-ionq

Added support for expressing IonQ Pauli-exponential gates. Fixed a bug in the computation of inverse MSGate.

cirq-web

Improved the cirq-web package layout to avoid installing the unnecessary cirq_ts module.

cirq - v1.5.0

Cirq v1.5.0 release

Summary

Added support for Python 3.13 and NumPy-2. Deprecated the Cirq-Rigetti package, which was changed to an opt-in component of the Cirq suite.

Deprecation of Cirq-Rigetti

The Cirq-Rigetti subpackage has been deprecated. For more details or to provide feedback, see #7058. Cirq-Rigetti needs to be installed explicitly using pip install cirq-rigetti as it is not included with the cirq installation anymore. Note that installation of Cirq-Rigetti requires a downgrade to Python 3.12 and NumPy-1.

cirq-core

Added BitMaskKeyCondition to provide multiqubit classical control conditions with bit masks. Added support to concatenate parameter sweeps as a new sweep. Added preliminary support for parsing OpenQASM-3. Improved MatrixGate decomposition to compensate for global phase change. Added function for computing Rényi entropy. Added transformers for cphase gauge transformation, simulation of depolarizing noise, and for performing randomized measurement protocol. Added contrib utilities for readout error benchmarking and an experimental workflow for Z-phase calibration of two-qubit gates.

API change

In next release the default value of the use_repetition_ids argument of the CircuitOperation will change from True to False. Please pass an explicit use_repetition_ids=True to preserve the current behavior of the code.

cirq-google

Enhanced serialization capability to support more circuit objects and parameter types for the cirq-google service backend. Added support for stimcirq gates and operations. Enhanced sweep proto messages with typed units and optional metadata. Added support for custom device parameter overrides for circuit execution.

cirq-ionq

Added definitions for the IonQ ZZGate and for device gatesets AriaNativeGateset and ForteNativeGateset. Added capability for circuit transpilation to native gatesets.

cirq - v1.4.0

Cirq v1.4.0 release

Summary

Added support for Python 3.12 and increased minimum Python version to 3.10.

Removal of cirq-ft

The cirq-ft package introduced in 1.2.0 was deleted after its move to the Qualtran repository at https://github.com/quantumlib/Qualtran.git. Please use that repository for fault-tolerant resource estimation needs.

cirq-core

Added cirq.UniformSuperpositionGate for creating uniform superposition from a subset of n-qubit basis states. Added transformer that implements dynamical decoupling for idle moments in a circuit. Added cirq.UNIT_SWEEP as an alias for the cirq.UnitSweep but with a constant-style name. Exposed the Mølmer–Sørensen MSGate at the top level cirq namespace.

cirq-google

Removed functions create_calibration_program and create_batch_program. Added tag class FSimViaModelTag to enable execution of the FSimGate using polynomial model.

cirq - v1.3.0

Cirq v1.3.0 release

Summary

Deprecation of cirq-ft

The newly created cirq-ft package (from 1.2.0) will be moving to its new home in the qualtran repository. Please pull from that repository to get all your fault-tolerant resource estimation goodness.

Qubit management

Two new qubit managers (GreedyQubitManager and SimpleQubitManager) can help manage creation and allocation of temporarily or borrowed ancilla qubits.

Performance improvements

Many minor performance improvements have been made over the past 6 months to help speed up troublesome corner cases, such as json serialization, transformers, circuit creation, and symbol resolution.

A classical simulator for simulating circuits without superposition (such as Toffoli, CNOT, X, SWAP, etc) has been added.

cirq - v1.2.0

Cirq v1.2.0 release

Summary

This Cirq release focuses on making it easier to express and do resource estimations for Fault Tolerant Quantum Algorithms, with a number of high level improvement summarized as follows:

Improvements to Cirq-Core

• Cirq protocols (eg: cirq.unitary) and simulators (eg: cirq.Simulator) now support gates that allocate new qubits as part of their decomposition
• cirq.QubitManager is a new top-level abstraction that defines the interface for a qubit allocator/deallocator which can be used to manage ancilla qubits at the time of circuit construction.
• cirq.decompose infrastructure is updated s.t. new composite gates can override the _decompose_with_context_ method to gain access to a cirq.DecompositionContext that contains options such as a cirq.QubitManager to help with allocating ancilla qubits at the time of circuit construction.

Cirq-FT: A new sub-package for Fault-Tolerant algorithms

Cirq-FT is a new sub-package for rapid prototyping and resource estimation of fault tolerant algorithms that extends Cirq. Some notable features include - A concept of qubit Register / Registers that make it easier for composite gates to express their signature in terms of named groups of logical qubits. - A cirq_ft.GateWithRegisters base class, which acts as a SHIM on top of the flat qubits API of cirq.Gate class and helps users define their composite gates using qubit registers. - New protocols, like cirq_ft.TComplexity, for macroscopic resource estimation. - New compilation transformers for mapping ancilla allocation / deallocation requests in a compute graph (eg: cirq circuit) to physical qubits, supporting both clean and dirty allocations. - A well-annotated and well-tested library of hierarchical gate decompositions which implements all the circuit primitives from Encoding Electronic Spectra in Quantum Circuits with Linear T Complexity. Table IV containing resource estimates of circuits with ~10^10 T-gates can be reproduced in under a minute demonstrating the scalability of the framework.

Other notable changes

• Dropped support for Python 3.7 and Python 3.8 and added support for Python 3.11
• Performance improvements for parameter resolution and a new __cirq_debug__ flag that provides an option to disable validations at the time of circuit construction.

cirq - Cirq v1.0.0

What's new

Cirq has officially left alpha and is v1.0. With this release comes new policies on API stability as well as functionality gaurantees for the long term. Along with some minor bug fixes and tweaks, this release focuses on stabilizing the APIs within cirq-core. With cirq-core we intend to follow along with semver and only make breaking changes with moves to new major versions. For the vendor packages we plan to continue to allow developers to iterate at speed and will do best effort on ensuring any API changes come with as little friction as possible. For all the details on this policy please see: release.md.

To make this upgrade as smooth as possible, we recommend first upgrading your installation to Cirq v0.15 to surface any deprecation warnings or upcoming breakages you might experience, once those are resolved, you can safely install Cirq v1.0.0.

Thank you all so much for your hard work.

cirq - Cirq v0.15.0

Cirq v0.15.0 release

Summary

This Cirq release focuses on fine tuning user APIs and library organization, with no new major feature additions. This release features lots of deprecations and long standing bug fixes in anticipation of the upcoming Cirq 1.0 release as well as a few refactors. This release fixes over 150 oustanding issues in Cirq and stabilizes many of the rough edges in the library. In upgrading to 1.0 it is recommended to first upgrade to this version to receive deprecation warnings for any changed functionality before moving to Cirq 1.0

Cirq v0.14.0 release

Highlights

Transformers

Revamped and deprecated many of the old and buggy optimizers found in cirq.optimizers with new cirq.transformer implementations. New transformers have well defined functionality with CircuitOperations and should be easier to use overall.

Classical Control

Cirq now has support for classical control in NiSQ relevant regimes. Classically controlled operations and measurement feedforward operations are supported. Extension into arbitrary classical logic on top of this is not on the immediate roadmap.

Devices

Devices have undergone a rework. Functionality to: attach a device to a circuit, use a device as a means to decompose a circuit, and exploration related functions have been removed. Devices now validate circuits and carry a DeviceMetaData property if more description of the device is needed.

Misc

In addition to the larger changes mentioned above, this release also includes new experiment utilities for characterizing device readout errors with cirq.measure_confusion_matrix. The cirq.decompose function contract has now been tightened to return a circuit containing just X,Y,Z,C*Z gates (assuming a decomposition is possible). Repeated measurement keys will now store temporal measurements (where previously they would be disallowed). New simulation techniques based on (https://arxiv.org/abs/2112.08499) and more.

cirq - Cirq v0.13.1

This release removes the measurement_key and measurement_keys protocols. These protocols were supposed to be removed in Cirq 0.13.0, but were missed.

Cirq v0.13.0 release

Highlights

ProjectorString + ProjectorSum

Added cirq.ProjectorString and cirq.ProjectorSum for compact representations and calculations involving projection operations.

Gatesets

Construct cirq.GateFamily and cirq.Gateset to test gates and operations for membership in well-defined groups.

NamedTopologies

Basic circuit to device placement routines (get_placements, draw_placements) have been added to Cirq, powered by NamedTopology.

Simulator performance improvements

Cirq's built-in simulators now dynamically factorize the simulated state into non-entangled subsets of qubits (when possible). This dramatically improves performance for circuits consisting of disconnected subsystems, and permits simulation of larger numbers of qubits for such circuits.

Clifford Tableau Decomposition

Upgraded existing clifford operations and circuits to make use of Tableau representation where appropriate and implemented baseline tableau to circuit decomposition using methods outlined in this paper.

Breaking changes

• Retain logofmeasurement_results throughout simulation (#4465):
  • Step results will include all measurements from previous moments in the simulation.
• Exponent should be drawn on target qubit in CX and CCX gates (#4462):
  • Tests depending upon diagrams of CX and CCX can now fail.
• Replace isinstance(op, GateOperation) checks in cirq_google optimizers to support other operation types (#4459):
  • Note that TaggedOperations which were earlier ignored by the optimizers would now be considered, and hence this is potentially a breaking change if people were implicitly relying on TaggedOperations not getting compiled by the optimizers.
• Resolve inconsistencies in using controlled gates & controlled operations (#4167):
  • gate_operation.controlled_by() can now return a cirq.GateOperation instead of cirq.ControlledOperation in cases where the underlying gates have specialized gate.controlled() implementations.
  • This also leads to a change in diagram of the controlled gates with specialized controlled implementations. For eg: Controlled S gate is now plotted as CZPowGate (@ --- @ ** 0.5) instead of ControlledOperation with Z ** 0.5 as subgate(@ ---- S)
  • op.controlled_by for 3Q gates like CCX, CCZ, CSWAP will now return ControlledOperation with sub_operation = <underlying non-controlled gate>. Eg: CCCX (i.e. sub_gate = X) instead of CTOFFOLI (i.e. sub_gate = TOFFOLI) etc.
  • Diagrams for ControlledOperations will now always have the exponent drawn on the target qubit (in case of multi qubit sub_operation, the exponent will always be on the first qubit if not the underlying gate does not explicitly specify a target index).

cirq - v0.12.0

Cirq v0.12.0 release

Highlights

All Cirq vendor modules have been extracted

Following the example of cirq-google now we have cirq.aqt, cirq.pasqal and cirq.ionq extracted to their corresponding new cirq modules. These are standalone packages that can be installed on their own with pip install cirq-<module>.

Rigetti support

In collaboration with Rigetti, the cirq-rigetti module is now avaiable to access the Rigetti QVM and Rigetti Quantum Computing Service runtimes.

Two-qubit unitary decomposition for (inverse) sqrt-iSWAP

Arbitrary two-qubit unitaries can be now decomposed to single and two-qubit gates using only 3 sqrt-iSWAP gates, compared to the previous 6 sqrt-iSWAP gates. This is an exact analytical compiler based on https://arxiv.org/abs/2105.06074

Typescript development and 3D Circuits

The cirq-web module adds the framework to develop new, interactive, Typescript based widgets for notebook environments. Two new widgets are added as an example: BlochSphere visualization and 3D Circuits.

Python 3.9 support

We now officially support python 3.9, it is included in our testing suite.

Performance boost for low entanglement circuits

Starting with https://github.com/quantumlib/Cirq/pull/4100 all simulators now dynamically allocate/deallocate memory when entangling between qubits or measuring/resetting qubits. This allows users to simulate larger number of qubits than otherwise would have been possible, with the requirement that not too much entanglement between qubits exist at any given moment in the circuit.

Breaking changes

• cirq.MergeInteractions behavior change (#4288):
  • MergeInteractions skips merging CZ gates if there are already equal or fewer in a sequence than the synthesized result (to prevent increasing the gate count). Previously, a tagged partial CZ gate could slip through and not be optimized even if allowpartialczs=False.
• changes in mutability of step_result.get_state(copy=False) (#4110):
  • Manual changes made to a step_result.get_state(copy=False) array are no longer preserved by default. If this behavior is required, it will continue to work if split_untangled_qubits=False, but this PR sets split_untangled_qubits=True.

Warning: Please make sure to uninstall all older (<0.11) versions of Cirq otherwise pip install cirq will result in an invalid installation where cirq is an empty namespace package. If you have older versions, run pip uninstall cirq before upgrading.

Highlights

Modular Cirq

We introduced a new structure, where cirq.google is now extracted to a separate package cirq-google, cirq itself became cirq-core and the cirq metapackage only contains these two subpackages as dependencies. The package extraction was done in a backwards compatible way - existing code that uses cirq.google will still run! However, you will get a DeprecationWarning. In order to switch over, ensure that you have cirq-google installed and change import cirq.google to import cirq_google. Everything else should work!

Histograms

• We have support for integrated histograms or CDFs to display characterization metrics from quantum chips

Breaking changes

• as mentioned in the top notice, pip install --upgrade cirq will not suffice to upgrade cirq - please run pip uninstall cirq before upgrading.
• cirq.rx, ry and rz are now returning a new class cirq.Rx, Ry and Rz respectively. This should work in most cases, unless your code explicitly depends on the type of the return value.
• cirq_google.SQRT_ISWAP_PARAMETERS got renamed to cirq_google.SQRT_ISWAP_INV_PARAMETERS
• cirq.Heatmap.plot() now takes all valid heatmap config arguments as **kwargs instead of just **collection_options, which is now a nested config argument (dict). Please see the tests / tutorials for more details.

Removed objects that were deprecated

• Removed support for the func parameter in Circuit.transform_qubits(), you now must use qubit_map instead
• TrialResult is now officially unsupported, use cirq.Result instead. If you have old JSONs lying around, you can just search and replace TrialResult to Result
• If you have old gate implementations with _resolve_parameter that doesn't support the recursive parameter, you will get an error message: TypeError: _resolve_parameters_() takes 2 positional arguments but 3 were given, you will need to add support for the recursive:bool parameter
• Removed support for the density_matrix parameter in cirq.von_neumann_entropy you now must use state instead
• stabilizers and destabilizers methods are now removed from the CliffordSimulator class, you can find these on the CliffordTableau instead
• perform_measurement is now renamed to apply_measurement in CliffordSimulator
• When implementing a subclass of the Simulator class, _simulator_iterator won't work, you will have to use _base_iterator
• cirq.vis.heatmap.relative_luminance is now moved to cirq.vis.relative_luminance

Objects or parameters that are marked as deprecated and will be removed in coming releases

• cirq.study.visualize.plot_state_histogram was moved to cirq.vis.plot_state_histogram
• cirq.google, deadline v0.14
• cirq.sim.clifford.CliffordTableau moved to a different package, you should use cirq.CliffordTableau instead
• cirq.contrib.routing.xmon_device_to_graph is deprecated, use cirq.contrib.grid_qubits_to_graph_device instead
• cirq.contrib.quantum_volume parameter device_or_qubits is deprecated, use device_graph instead.

cirq - Cirq v0.10.0

Cirq v0.10.0 release

Major usability changes

Cirq core

• We now have support for TwoQubitHeatmaps. Single qubit Heatmaps are also easier to use.
• Add PauliSumExponential for commuting Pauli terms (#3427)
• Circuit transformations:
  • realign operations: cirq.AlignLeft, cirq.AlignRight
  • concatenate multiple circuits via cirq.Circuit.tetris_add
• You can now decompose arbitrary 3 qubit unitaries with cirq.three_qubit_matrix_to_operations
• JSON serialization now supports GZIP
• Create more structure in your circuits by using subcircuits with cirq.CircuitOperation

Platforms

• cirq.ionq (NEW!):
  • We proudly announce our IonQ integration - Have a look at the tutorials!
• cirq.google:
  • Introduced tools for Floquet Calibration

Contrib

• [new!] We introduced a new matrix product state representation based simulator: cirq.contrib.quimb.MPSSimulator

Breaking changes

• Heatmap is redesigned and configuration parameters are now passed via **kwargs instead of setter/getter functions.
• cirq.experiments changes: the default value of the parameter two_qubit_op_factory in random_rotations_between_grid_interaction_layers_circuit and random_rotations_between_two_qubit_circuit changed to cirq.CZ instead of cirq.google.SYC
• cirq.google.api.v2.results.MeasureInfo is now a dataclass which also contains tags corresponding to the circuit passed to cirq.google.api.v2.find_measurements.
• cirq.CliffordSimulator behavior changed: if you relied on the old (incorrect) ability to mutate the simulator state from a step result, your workflow would be broken by this. (see #3664 for details)
• measurement_keys protocol now returns AbstractSet[str] instead of Tuple[str, ...]
• cirq.resolve_parameters changes - in most cases you should not see a change (see #3546 for details):
  • Parameter resolution no longer depends on alphabetization of parameters involved - see #3544 for an example
  • Cirq will raise a RecursionError when encountering a loop in parameter resolution
  • Resolver is more zealous in its conversion of int to float
• cirq.protocols.json_serialization.RESOLVER_CACHE goes away -- you should not see a change in most cases is it was not a part of the public API.

New protocols

• read_json_gzip
• resolve_parameters_once
• SerializableByKey
• to_json_gzip

Changes to top level objects

New top level objects

• AbstractCircuit
• Alignment
• CircuitOperation
• ionq
• FrozenCircuit
• PauliSumExponential
• PhasedFSimGate
• wait
• AlignLeft
• AlignRight
• two_qubit_matrix_to_diagonal_and_operations
• three_qubit_matrix_to_operations
• density_matrix
• QUANTUM_STATE_LIKE
• QuantumState
• quantum_state
• validate_density_matrix
• read_json_gzip
• resolve_parameters_once
• SerializableByKey
• to_json_gzip
• with_measurement_key_mapping
• TwoQubitInteractionHeatmap

Removed top level objects that were deprecated - subwavefunction - wavefunction_partial_trace_as_mixture - QFT - decompose_two_qubit_interaction_into_four_fsim_gates_via_b - validate_normalized_state - final_wavefunction - SimulatesIntermediateWaveFunction - WaveFunctionSimulatorState - WaveFunctionStepResult - WaveFunctionTrialResult - has_mixture_channel - mixture_channel

Top level objects or parameters that are marked as deprecated and will be removed in coming releases

• parameter deprecation:cirq.Circuit.transform_qubits Use qubit_map instead of func
• parameter deprecation:cirq.Moment.transform_qubits Use qubit_map instead of func
• parameter deprecation:cirq.Operation.transform_qubits Use qubit_map instead of func
• parameter deprecation:cirq.von_neumann_entropy Use state instead of density_matrix
• cirq.CliffordState.perform_measurement
• cirq.SimulatesIntermediateState._simulator_iterator
• cirq.vis.heatmap.relative_luminance

cirq - Cirq v0.9.1

This point release fixes the deprecation of cirq.TrialResult to cirq.Result in a backward compatible way with regards to the JSON parsing as well. There are no changes in any other user-facing functionality.

No other changes to cirq functionality. No protocol changes, top-level changes or other changes.

cirq - Cirq v0.9.0

Major usability changes:

• Batching support in Google's Quantum Engine API as well as in Samplers in general
• Faster parameter resolution for a wider set of types
• You can now use cirq.parameter_names, cirq.parameter_symbols to extract parameter names from your circuit
• Default values for Arg serializers are being introduced in two steps: first the deserializer (#3280), later the serializer will be introduced
• Extensive documentation on Pasqal
• Extensive documentation on Google's Quantum Computing Service
• Google Quantum Engine can list jobs and programs
• Python 3.7 and 3.8 are now continuously tested and dependency issues are resolved
• Experimental support for Quimb Tensor Network Simulators (#3129)
• We removed wavefunction, wave_function, or state - now, state_vector is consistently used instead

Breaking changes: - cirq.approx_eq now raises an AttributeError if the symbolic evaluation can't unambiguously decide the equality, before it returned False #3195 - cirq.google.Engine methods run, run_sweep and create_program now raise ValueError if gate_set is not specified #3138 - cirq.google.Engine constructor signature change: context is now last to signal that direct usage isn't recommended #3151 - cirq.google.is_native_xmon_gate, cirq.google.is_native_xmon_op, cirq.google.pack_results, cirq.google.unpack_results are now removed, they are still accessible but through the deprecated cirq.google.api.v1.programs module #3204 - circuit + gate behavior changed, it won't create an extra moment, instead packs the new gate efficiently #3364

New protocols: - cirq.acton - cirq.pauliexpansion

cirq - Cirq v0.5.0

Themes:

• Noisy simulation.
• Experiments.
• Symbols via sympy.
• Algebraic manipulation of gates.
• Support for other hardware.

Notable new functionality:

• Added cirq.controlled_by protocol. Gates and operations now have a controlled_by method. ControlledGate and ControlledOperation support arbitrary numbers of controls.
• Added cirq.channel and cirq.mixture protocols for defining noisy evolution.
• Added cirq.DensityMatrixSimulator.
• Added cirq.NoiseModel/cirq.NO_NOISE/cirq.ConstantQubitNoiseModel classes. Some simulate and sample methods now take noise models.
• Added cirq.amplitude_damp, cirq.phase_damp, and other noise channels.
• Added convenience methods cirq.sample and cirq.sample_sweep for sampling from circuits without having to explicitly pick a simulator.
• Added cirq.experiments package with rabi_oscillations, single_qubit_randomized_benchmarking, and other predefined experiments.
• cirq.X, cirq.Y, and cirq.Z are now cirq.Pauli instances, whose operations can be multiplied together to produce cirq.PauliStrings.
• Added cirq.pauli_expansion protocol
• cirq.PauliString now supports exponentiation and raising to a power. The expression np.exp(1j * np.pi / 3 * cirq.X(q1) * cirq.Y(q2)) produces an operation you can append into a circuit.
• Added cirq.LinearDict for representing linear combinations.
• cirq.Gate instances can now be scaled and added together, producing a cirq.LinearCombinationOfGates.
• The unitary protocol now falls back to decompose, allowing gates to be defined using only a _decompose_ method.
• cirq.approx_eq now works on circuits and gates
• cirq.value_equality now has an approximate flag, and there is now cirq.PeriodicValue for handling approximate angles.
• All methods that take a parameter resolver can now take a raw dictionary and default to the empty resolver.
• Gates can now be parameterized using arbitrary sympy expressions.
• Added cirq.testing.random_superposition
• Added cirq.NamedQubit.range.
• Added cirq.IdentityGate and the single-qubit identity gate cirq.I.
• Added cirq.IonDevice and cirq.NeutralAtomDevice and related helper methods.

Notable breaking changes:

• cirq.QubitId has been renamed to cirq.Qid.
• SingleQubitGate.on_each now takes a varargs *targets instead of a targets list.
• All cirq.Gate instances must now implement a num_qubits method. cirq.MeasurementGate's first argument is now the number of qubits. Use cirq.measure instead.
• cirq.Tolerance has been deleted, replaced by explicit atol/rtol arguments.
• cirq.Symbol has been deleted, replaced by sympy.Symbol.
• cirq.google.XmonSimulator no longer does automatic decomposition of circuits, which was hidden from and surprising to users. Circuits given to the xmon simulator must now only use supported operations. Use cirq.Simulator or cirq.sample instead.
• Deleted cirq.contrib.jobs package, which was obsoleted by the introduction of cirq.NoiseModel.

cirq - Cirq v0.4.0

Themes:

• Making the API more pythonic and more consistent (a.k.a. breaking changes and refactoring)
• Faster simulation

Notable new functionality:

• cirq.Rx, cirq.Ry, and cirq.Rz
• cirq.XX, cirq.YY, cirq.ZZ, and cirq.MS (Mølmer–Sørensen gate)
• cirq.Simulator
• cirq.SupportsApplyUnitary protocol for specifying fast simulation methods

Notable breaking changes:

• Most gate classes have been standardized to take an exponent argument and have a name of the form NamePowGate. For example, RotXGate is now XPowGate and no longer takes rads, degs, or half_turns.
• The xmon gate set has been merged into the common gate set.
• Capability marker classes have been replaced by magic method protocols. For example, gates now just implement a _unitary_ method instead of inheriting from KnownMatrix.
• cirq.Extensions and cirq.PotentialImplementation are gone.
• Several decomposition classes and methods have been moved from cirq.google.* to cirq.*. For example,cirq.google.EjectFullW is now cirq.EjectPhasedPaulis.
• Moved classes and methods related to line placement into cirq.google.

Notable bug fixes:

• Two qubit gate decomposition no longer produces a glut of single qubit gates.
• Circuit diagrams stay aligned when given multi-line entries, and now include "same moment" indicators.
• Fixed false-positives and false-negatives in cirq.testing.assert_circuits_with_terminal_measurements_are_equivalent.
• Fixed many repr methods returning code that assumed from cirq import * instead of import cirq.
• Example code now runs in both python 2 and python 3 without transpilation.

Notable dev changes:

• Test files now import cirq instead of specific modules.
• Better testing and packaging scripts.
• No longer using different package versions for python 2 and python 3
• cirq.value_equality decorator.
• New cirq.testing methods and classes.

Additions to contrib:

• cirq.contrib.acquaintance: utilities for defining permutation gates
