0.21.0 (September 2023)#

  • Ensure results retrieval works even with an old-format ResultHandle (generated by a pre-0.17.0 version of pytket-quantinuum).

  • Add properties QuantinuumBackend.default_two_qubit_gate and QuantinuumBackend.two_qubit_gate_set providing the default and supported two-qubit gates for a device.

  • Add QuantinuumBackendCompilationConfig dataclass, which can be passed as an optional argument when constructing a QuantinuumBackend. Configuration can be inspected using QuantinuumBackend.get_compilation_config() and modified using the methods QuantinuumBackend.set_compilation_config_allow_implicit_swaps() and QuantinuumBackend.set_compilation_config_target_2qb_gate().

  • Add optional argument allow_2q_gate_rebase argument to process_circuit(), process_circuits() and submit_program() to allow the backend to rebase to rebase the circuit to a different two-qubit gate judged to have better fidelity before being run. The default is to not allow this.

  • Fix handling of multiple classical registers when submitting QIR.

0.20.0 (August 2023)#

  • Add leakage_detection option to QuantinuumBackend.process_circuits() that automatically modifies Circuits with ancillas for detecting leakage errors. Also provides a new method prune_shots_detected_as_leaky for removing erroneous shots from BackendResult.

0.17.0 (June 2023)#

  • Add Language enum to control language used for circuit submission, with values Language.QASM and Language.QIR.

  • Renamed QuantinuumBackend.submit_qasm() to QuantinuumBackend.submit_program(), with a language argument.

  • Add a language kwarg to QuantinuumBackend.process_circuits(), defaulting to Language.QASM. (Support for Language.QIR is experimental and its use is not recommended; a warning will be emitted. You must install the pytket-qir package separately in order to use this feature.)
