Changelog

Version 1.1.0

  • Migrated to Qiskit 1.3 :
    • Default optimization_level for backend.transpile() is changed from 1 to 2.
  • Transpilation now works correctly for backend targets with only Clifford + T gate basis (except for gates CRY, RCCX and RCCCX on macOS for now)
  • Alice & Bob custom options like average_nb_photons are not allowed for backend.run() with local provider because they will be ignored. They should be passed to provider.get_backend() instead.
  • Drop support for Python 3.8

Version 1.0.0

  • Migrated to Qiskit 1.2 (BREAKING CHANGES for 1.0) :
    • Function execute() is removed in favor of transpile() + backend.run()
    • circuit.cnot() gate should now be declared with circuit.cx()
    • Python environments created with previous Qiskit versions need to be recreated
    • For more details about other Qiskit 1.0 changes, you can read the complete migration guide.
  • Specifying options for get_backend() no longer modifies the default options for this backend on the Alice & Bob provider Python object.

Example to execute a circuit :

# Legacy path
from qiskit import execute

job = execute(circuit, backend)

# New path
from qiskit import transpile

new_circuit = transpile(circuit, backend)
job = backend.run(new_circuit)

Version 0.7.2

  • Bump twine to version 5.1.1

Version 0.7.1

  • Use ipywidget to display job status on notebooks

Version 0.7.0

  • Deprecated Python 3.7 for the provider. Python 3.7 has been officially deprecated since June 27th 2023. (https://devguide.python.org/versions/) This was triggered after ARM chip users experienced issues with installing the provider since Numpy is not built for ARM Python 3.7.
  • Set max version of Python to 3.11 for the provider. Python 3.12+ introduces breaking changes to setuptools. The Alice & Bob team will support this version in the near future.
  • Changed default remote API URL to api-gcp.alice-bob.com instead of api.alice-bob.com, following the official release of Felis Cloud on Google Cloud Platform. GCP is now the main point of entry to use Felis Cloud.
  • Added a warning when instancing the AliceBobRemoteProvider if a new version of the provider is available on pypi.

Version 0.6.0

  • Improved feedback while running circuits using the remote provider

Version 0.5.4

  • Add support for the TDG gate for the logical backends of the remote provider (the TDG gate was already supported on the local provider)

Version 0.5.3

  • Fix a transpilation issue that prevented the usage of logical backends with the remote provider.

Version 0.5.2

  • Fix a transpilation issue for the logical backends, preventing the transpilation of circuits using a cswap gate.

Version 0.5.1

  • Improved transpilation and scheduling for the local backends, to better support programs imported from QASM code.

Version 0.5.0

  • Harmonized the get_backend functions of the remote and local provider to act in a similar manner. The following line is now working as it does for local:
remote_provider.get_backend('EMU:6Q:PHYSICAL_CATS', average_nb_photons=4.5, kappa_1=1000)

Version 0.4.2

  • Released multi-qubits logical and physical targets for the remote provider, allowing to run these models remotely.

Version 0.4.1

  • Added support for Python 3.11

Version 0.4.0

  • Added logical backends: EMU:15Q:LOGICAL_EARLY and EMU:40Q:LOGICAL_TARGET
