Recent Releases of qsharp

qsharp - v1.20.0

Below are some of the highlights for the 1.20 release of the QDK.

QIR target profile selection redesign

In previous releases, the target QIR profile setting for code generation in VS Code was a global setting, and if switching between projects with different target profiles the user would need to remember to change the editor setting each time. This was cumbersome and a common source of confusion.

With this release, the target profile can be set per project. If working on a multi-file project with a qsharp.json manifest file, the target profile can be specified in the manifest file via the "targetProfile" property.

If working in a standalone Q# or OpenQASM file, the target profile can be specified via the @EntryPoint attribute in Q# files, or the qdk.qir.profile pragma in OpenQASM files. For example, to target a Q# file for base profile code generation:

qsharp @EntryPoint(Base) operation Main() : Result[] { // ... }

If submitting a job to the Azure Quantum service, upon submission the target profile will default to the capabilities of the target hardware if not otherwise specified.

See the QDK Profile Selection wiki page for more details and examples.

OpenQASM improvements

Arrays and complex numbers can now be passed as input and output.
Qubit aliases and array concatenation are now supported.
In VS Code, OpenQASM files now support:
- Rename symbol (F2) for user-defined identifiers, gates, functions, etc; built-ins are not renameable.
- Go to Definition (F12) and Find All References (Shift+F12).
The GitHub Copilot tools for the QDK now support OpenQASM (.qasm) files as well as Q#. You can simulate your program, generate a circuit diagram and generate resource estimates for Q# and OpenQASM programs right from the chat panel.

Python interop improvements

In addition to primitive types, arrays, and tuples, users can now pass Q# structs. For example, the following shows passing a python object to a Q# operation that takes struct:

Complex numbers are also supported, allowing the passing of Python complex literals and variables directly to Q# callables, e.g.

```python import qsharp

qsharp.eval(""" import Std.Math.Complex;

function SwapComponents(c: Complex) : Complex {
    new Complex { Real = c.Imag, Imag = c.Real }
}
""")

from qsharp.code import SwapComponents assert SwapComponents(2 + 3j) == 3 + 2j ```

For more details on Python and Q# interop see our wiki page.

Richer Copilot help for Q# APIs

In this release, we added a new Copilot tool that can access the documentation generated by all the APIs available in the current project (included the standard library and referenced libraries). This lets Copilot see up-to-date information on the Q# libraries available and how to use them, improving Copilot's working knowledge of Q#. From generated Q# snippets to answering questions about available APIs, Copilot can use this to provide more accurate and up-to-date information.

Language service improvements

Numerous improvements to the language service have been made for correctness and completeness, especially around import and export declarations. The language service now also provides better diagnostics for QIR generation errors. Please log issues if you encounter any problems!

qsharp - v1.19.0

Below are some of the highlights for the 1.19 release of the QDK.

Simulating qubit loss

Simulation in the QDK can now model qubit loss, which can occur with some probability on some modalities.

For simulations run directly in VS Code, such as using the 'Histogram' CodeLens, this can be controlled via a VS Code setting. The screenshot below shows setting qubit loss to 0.5% and running a Bell pair simulation. For convenience, the VS Code setting is easily accessible from a link on the histogram window (shown in a red circle below).

The qubit loss probability can also be specified if running a simulation via the Python API.

python result = qsharp.run("BellPair()", 100, qubit_loss=0.5) display(qsharp_widgets.Histogram(result))

There is also a new Q# API for detecting a loss result:

qsharp operation CheckForLoss() : Unit { use q = Qubit(); H(q); let res = MResetZ(q); if IsLossResult(res) { // Handle qubit loss here } else { // Handle Zero or One result } }

You can find more details in the sample Jupyter Notebook at https://github.com/microsoft/qsharp/blob/main/samples/notebooks/noise.ipynb.

Debugger improvements

When debugging, previously if you navigated up the call stack using the area circled below, the Locals view would not change context to reflect the state of the variables in the selected stack frame. This has now been implemented.

Call stacks reported when a runtime error occurs now also show the source location for each frame in the call stack.

OpenQASM improvements

We have continued to improve support for OpenQASM. For example, you can now use readonly arrays as arguments to subroutines and the builtin sizeof function, which allows you to query the size of arrays.

```qasm def staticarrayexample(readonly array[int, 3, 4] a) { // The returned value for static arrays is const. const uint dim1 = sizeof(a, 0); const uint dim2 = sizeof(a, 1); }

def dynarrayexample(readonly array[int, #dim = 2] a) { // The 2nd argument is inferred to be 0 if missing. uint dim1 = sizeof(a); uint dim2 = sizeof(a, 1); } ```

This release also adds many other built-in functions, as well as pragmas to specify the semantics and code generation for box statements.

For more examples of the OpenQASM support see the samples at https://github.com/microsoft/qsharp/tree/main/samples/OpenQASM or the Jupyter Notebook at https://github.com/microsoft/qsharp/blob/main/samples/notebooks/openqasm.ipynb.

Test improvements

A challenge when writing tests for code intended to run on hardware was that the test code would also be restricted to what could run on hardware. For example, if the target profile is set to base then mid-circuit measurements and result comparisons are not possible, which limits the validation a test can do. Trying to verify a measurement result in a test would previously result in errors such as using a bool value that depends on a measurement result is not supported by the configured target profile.

In this release we have relaxed the checks performed on code marked with the @Test attribute, so such code is valid regardless of the target hardware profile:

Azure Quantum job reporting

When submitting jobs to Azure using the VS Code "Quantum Workspaces" explorer view, previously jobs would use the v1 reporting format, which does not include details for each shot's results. The default format for job submission in this release is now v2, which includes the results of each shot.

We also added an additional icon beside successfully completed jobs so the results may be shown as a histogram or as the raw text. The below screenshot shows fetching both formats from a completed job.

qsharp - v1.16.0

We are excited to release v1.16 of the Quantum Development Kit. The big features of this release are:

Copilot integration

With VS Code Copilot integration you can now use Copilot to to assist with many tasks such as writing code, generating tests, connecting to an Azure Quantum workspace, submit jobs to run on hardware, and more!

See the wiki page at https://github.com/microsoft/qsharp/wiki/Make-the-best-of-Q%23-and-VS-Code-agent-mode for more info, as well as tips and best practices.

Circuit Editor

You can now add .qsc files to your project which provide a drag-and-drop circuit editor user interface to create quantum operations, which can then be called from your Q# code.

See the wiki page at https://github.com/microsoft/qsharp/wiki/Circuit-Editor for more details.

Notable Changes

New `QuantumArithmetic` library

This release is the first to add the QuantumArithmetic library by @fedimser to the list of suggested libraries! Check out more about the library at https://github.com/fedimser/quant-arith-re.

Measurement and qubit reuse decompositions handled in QIR generation

This change addresses a long-standing point of confusion regarding how programs compiled for QIR Base profile are displayed in places like the circuit visualizer. By delaying application of decompositions for deferred measurement and avoidance of qubit reuse to the QIR generation step, the stdlib implementation of measurement no longer needs to have a different implementation for Base profile vs other profiles. This should make the displayed circuits match the written code more often. See #2230 for more details.

qsharp - v1.13

We are excited to release v1.13 of the Azure Quantum Development Kit! Here are some highlights of features included in this month's release:

`@Test` Attribute and VS Code Test Explorer Integration

2095 Introduced a new attribute, `@Test`, which identifies unit tests written in Q#. By integrating with the Text Explorer feature in VS Code, you can now explore, run, and review Q# unit test execution:

See the wiki page on Testing Q# Code in VS Code for more information.

"Q#: Add Project Reference" VS Code Command Enhancements

2079 enhanced the VS Code command for adding references to a Q# project, available when editing a `qsharp.json` file:

When invoking the command, you'll now see a choice to either import from GitHub or search the currently opened workspace for other Q# projects. When choosing GitHub, you'll get a suggestion of known libraries and their available versions to choose from, and the corresponding external project reference snippet will automatically be added to your current qsharp.json:

More Python Interoperability for Callables

2091 added more support for using Python functions that wrap Q# callables across our Python package APIs. This makes it easier to pass Python arguments into Q# for features like resource estimation with `qsharp.estimate()`, running multiple shots with `qsharp.run()`, compiling to QIR with `qsharp.compile()`, or generating circuits with `qsharp.circuit()`:

For more information on using Q# callables directly in Python, see the Invoking Q# Callables from Python wiki page.

Adaptive Profile Floating-Point Computation Extension

2078 added support for an additional QIR Adaptive profile extension: floating-point computation. By choosing `QIR Adaptive RIF` as your compilation profile, you can enable Reset, Integer computation, and Floating-point computation for code generation. This allows you to write programs where the values of variables with Q# type `Double` can be dyanmically calculated from measurement results at runtime, and the output QIR will include arithmetic and comparison instructions corresponding to your code, enabling even more adaptive algorithms.

Note that this profile extension must be supported by the target backend or runtime environment for the resulting code to execute. See the QIR specification section on Classical Computation extensions to the Adaptive profile for more details.

qsharp - v1.12

We are excited to release v1.12 of the Azure Quantum Development Kit! Here are some highlights of features included in this month's release:

Python interoperability improvements

You can now import and invoke your Q# callables for simulation directly from Python as functions. Your callables defined in %%qsharp magic cells, through calls to qsharp.eval, or loaded from projects in qsharp.init can now be imported from the qsharp.code module: ```python import qsharp

qsharp.eval(""" operation Superposition() : Result { use q = Qubit(); H(q); Std.Diagnostics.DumpMachine(); MResetZ(q) } """)

from qsharp.code import Superposition result = Superposition() ``` For more details and current limitations, see Invoking Q# callables from Python in the wiki.

Syntax for capturing state dumps from DumpMachine or DumpRegister and operation matrices from DumpOperation calls in your Q# code has also been improved (see #2042)

Deprecation of `set` keyword

The set keyword used for updating mutable values is now deprecated, so where you previously had to use set x += 1 you can now just write x += 1. In addition, the compiler includes a new lint that defaults to "allow" that you can use to warn or error on usage of set in your code (see #2062).

`ApplyUnitary` operation for simulation

When running against the simulator, your Q# code can call ApplyUnitary and pass a unitary matrix represented by a Std.Math.Complex[][] along with an array of qubit targets and have the simulator directly apply that unitary to the current sparse state vector.

Increase minimum versions for Python and Ubuntu

Starting with v1.12, the minimum supported Python version for the qsharp package is Python 3.9. Along with this change, the minimum compatible version of Ubuntu has been increased to 22.04 (see #2061)

qsharp - v1.11.1

We are excited to release v1.11.1 of the Azure Quantum Development Kit! This month's release includes features and bug fixes, such as:

Configure Pauli Noise Dynamically within Q

You can now use the ConfigurePauliNoise function to dynamically update noise settings during simulation, allowing samples, exercises, or test code to directly set noise used in testing (https://github.com/microsoft/qsharp/pull/1997).

Stabilization of the Microsoft.Quantum.Unstable libraries

The Arithmetic, StatePreparation, and TableLookup libraries have been stabilized and are now available under Std. Several samples and libraries have been updated to reflect the new location, while the Microsoft.Quantum.Unstable namespace will be preserved for backward compatibility (https://github.com/microsoft/qsharp/pull/2022, https://github.com/microsoft/qsharp/pull/2043).

Support for Qiskit v1.3.0

Changes made to the Qiskit target class in v1.3.0 that broke interoperability with the qsharp Python package are now handled dynamically allowing use of both v1.2 and v1.3 versions of Qiskit (https://github.com/microsoft/qsharp/pull/2050).

qsharp - v1.10.1

We are excited to release v1.10 of the Azure Quantum Development Kit! This month's release includes several new features and improvements including:

Code editing improvements

Code editing is now greatly improved. A couple of examples of the many improvements:

Context aware completions (#1947) show only the relevant completions for the location. For example, only showing types when in a type position:

Namespace member (#1947) completion lists are now provided when drilling into namespaces:

User Defined Type (#1954) member completions are now populated

And much more! Parser error recovery has also been greatly improved so that editor assistance is available whilst mid-edit in many more scenarios.

Noisy simulation

You can now add Pauli noise to simulations run from Python or VS Code (#1971, #1975, #1980). This can help model the results of running on a real quantum machine for education purposes, and to help develop and test the effectiveness of error correction.

Below shows the results of configuring 5% bit-flip noise in VS Code and running a histogram on the GHZ sample. This would return only $\ket{000}$ and $\ket{111}$ shot results if run in a noise free simulation.

To see how to use noisy simulation in Python, check out the sample notebook at https://github.com/microsoft/qsharp/blob/main/samples/notebooks/noise.ipynb

Refreshed API docs interface

The in-editor Q# API documentation has had a UI refresh (#1978). This is accessed via the "Q#: Show API documentation" command in the command palette when editing a Q# file. The new UX allows you to quickly & easily search & navigate the APIs within your project, referenced projects, and the standard library.

File icons

The Q# file extension (.qs) now gets a unique icon in VS Code (#1976)

Custom measurements and resets

Previously you could define custom gates, but not custom measurement or reset operations. With #1967, #1981, and #1985 this is now possible. This allows for the definition and use of custom operations for quantum simulation and QIR code generation.

Samples for this feature will be added shortly, in the meantime see the test code at https://github.com/microsoft/qsharp/blob/v1.10.1/compiler/qsc/src/codegen/tests.rs#L529 for an example of how this may be used.

Python telemetry

In this release we have added telemetry to our qsharp Python package to collect minimal and anonymous metrics on feature usage and performance. This will allow us to focus our investments going forward on the most valuable areas. Please see the notes in the package readme for details on what is collected and how to disable it.

qsharp - v1.9.0

The 1.9.0 release of the QDK includes interoperability with Qiskit circuits built upon the core Q# compiler infrastructure.

The Qiskit interop provided by the QDK includes:

Resource estimation for their Qiskit circuits locally
Q# Simulation of Qiskit circuits using Q#'s simulation capabilities
QIR generation from Qiskit circuits leveraging the modern QDKs advanced code generation capabilities.

The Qiskit interop wiki page provides a brief overview of the integration while detailed examples, potential errors, and usage with parameterized circuits are demonstrated in the sample Qiskit interop notebook.

In addition to the Qiskit interop feature, the language service for Q# will now auto-suggest the new standard library API instead of the legacy Microsoft.Quantum-prefixed standard library API. For example, when typing DumpMachine, you'll now get a suggested import for Std.Diagnostics.DumpMachine instead of Microsoft.Quantum.Diagnostics.DumpMachine.

qsharp - v1.7.0

QDK 1.7.0 release notes

The team is very excited to ship this release. It has some of the most significant improvements to the Q# language in a long time.

Major language changes

External project references

The biggest feature in this release is the ability to reference other projects and consume their APIs. The projects can be in a separate local directory or published to GitHub. As part of this change, we also introduced import and export syntax, and generate an implicit namespace hierarchy based on file layout, removing the need for the namespace syntax.

For more details see the wiki page at https://github.com/microsoft/qsharp/wiki/Q%23-External-Dependencies-(Libraries). (The official documentation will be updated shortly with more details and examples).

New struct syntax

We're also introducing a new struct syntax, and long term see this as the replacement for the current UDT syntax. The custom types created by either are largely compatible, but the new syntax is simpler, cleaner, and similar to several popular languages. See more details at https://github.com/microsoft/qsharp/wiki/Q%23-Structs until the official docs are updated.

Optional EntryPoint

As well as removing the need to wrap code in a namespace, we're also removing the need to specify the EntryPoint attribute. If you have one callable called Main in your project, this will be the default entry point. (Note: Any specified @EntryPoint will still take precedence).

A new standard library namespace

We've also simplified the namespaces for our standard library. What was previously all under Microsoft.Quantum can now be accessed under the Std namespace. This reduces visual clutter and highlights what APIs are part of the "standard" library included with Q#.

Example

Taken together the above provides for a much cleaner language with a simple code sharing mechanism. For example, if your project references another project named Sparkle which exports an operation named Correct that takes a custom type Input with a Double and a Qubit, your entire Q# code to call this can be as simple as:

```qsharp import Std.Diagnostics.DumpMachine; import Sparkle.Input, Sparkle.Correct;

operation Main() : Unit { use q = Qubit[1]; let x = new Input { A = 3.14, B = q[0] };

Correct(x);

DumpMachine();
MResetZ(q[0]);

} ```

(Note these changes are additional capabilities. There are no breaking changes or requirements to change code to adopt this release).

Other updates and improvements

Many other changes have gone into this release. Some of the main ones include:

Unitary Hack contributions
- Save RE widget to .png (#1604)
- Lint rule: Use Functions (#1579)
- Add doc for internal AND (#1580)

qsharp - v1.6.0

Welcome to the v1.6.0 release of the Azure Quantum Development Kit!

The big feature in this release is the ability to compile Q# programs to QIR that require "Adaptive Profile" capabilities. This enables programs to take advantage of the latest capabilities of quantum hardware, such as the ability to perform mid-circuit measurement of qubits, branch based on the results, and perform some classical computations at runtime. For more details, see https://aka.ms/qdk.qir.

We've added or updated a number of samples that can leverage Adaptive Profile capabilities, such as the Three Qubit Repetition Code and the Iterative Phase Estimation notebook. Please do try it out and give us your feedback!

As part of the above work, the previous code generation approach was replaced, even in the non-Adaptive ("base profile") case. Please log an issue if you see any unexpected change in behavior.

Other notable new features include Q# linting support in Jupyter Notebooks, CodeActions in VS Code to fix certain Q# errors, Q# library documentation inside VS Code, and more!
