  • API breaking changes

    • Renamed CuTensorNetBackend to CuTensorNetStateBackend.
    • Moved get_operator_expectation_value and get_circuit_overlap from backends submodule to general_state submodule.
    • Warning TensorNetwork object will soon be deprecated in favour of the new GeneralState.

  • New API: GeneralState for exact simulation of circuits via contraction-path optimisation. Currently supports get_statevector(), expectation_value() and sample().

  • New feature: CuTensorNetShotsBackend for simulation of circuit shots.

  • New feature: MPS algorithms MPSxGate and MPSxMPO now support simulation of two-qubit gates acting on non-adjacent qubits.

  • New feature: add_qubit to add fresh qubits at specified positions in an MPS.

  • New feature: added an option to measure to toggle destructive measurement on/off. Currently only supported for MPS.

  • New feature: a seed can now be provided to Config objects, providing reproducibility across StructuredState simulations.

  • New feature: apply_unitary both for MPS and TTN to apply an arbitrary unitary matrix, rather than a pytket.Command.

  • New feature: apply_qubit_relabelling both for MPS and TTN to change the name of their qubits. This is now used within simulate to take into account the action of implicit SWAPs in pytket circuits (no additional SWAP gates are applied).

  • Updated pytket version requirement to 1.30.
