qlass: A Python Package for Variational Quantum Algorithms on Photonic Devices - v0.2.0

In this release, we added many new functionalities and improvements in simulation of VQE's. For example, we added new initial states for ansatzes and ensembe VQE for support of multiple initial states. The simulation of VQE's using photonic unitary executors has been sped up significantly also. In the following, all the changes are listed.

qlass: A Python Package for Variational Quantum Algorithms on Photonic Devices - Version 0.1.4

This release is a minor update to the repository, mainly focussing on some technical improvements:

  • Added Code Coverage workflow
  • Improve tests to maximize code coverage (88% as of the latest version)
  • Added a one page white paper for submission to JOSS

qlass: A Python Package for Variational Quantum Algorithms on Photonic Devices - Version 0.1.3

In this release we have enhanced qlass by adding the following new functionality:

  • We have added a new submodule in the compiler module that aims to characterize particular photonic devices. The HardwareConfig class is a dataclass that contains relevant information for parameters of a physical linear optical circuits that determines their performance.
  • The compiler module has been updated to compute resource requirements and generate a report when compiling a qiskit circuit to a linear optical circuit. This information can be used to decide feasibility of running the circuit. This uses the newly added HardwareConfig class.
  • For implementing noisy simulations of linear optical circuits, mimicking real world usage of photonics, we updated the compile function to allow for compiling to noisy versions of a linear optical circuits given some perceval noise model. This allows us to do noisy simulations of linear optical circuits.

The documentation has been updated to reflect the new additions to qlass.

qlass: A Python Package for Variational Quantum Algorithms on Photonic Devices - Version 0.1.2

This milestone cointains many improvements mostly due to bounties being resolved during the unitartyHACK 2025. Among others, it includes:

  • a new function for implementing a custom unitary ansatz (PR by @Qubit1718)
  • OpenFermion as the standard library for working with Hamiltonians (PR by @Kitsunp)
  • generalizing the loss function to accept more general executors (PR by @Kitsunp)
  • improvements to the tutorial notebook (PR by @Qubit1718)
  • improving efficiency of evaluating Hamiltonains by grouping commuting Pauli terms (PR by @Kitsunp)
