API documentation¶

class pytket.extensions.pennylane.pytket_device.PytketDevice(wires, shots=None, pytket_backend=<pytket.extensions.qiskit.backends.aer.AerStateBackend object>, optimisation_level=None, compilation_pass=None)[source]¶

PytketDevice allows pytket backends and compilation to be used as Pennylane devices.

analytic_probability(wires=None)[source]¶

See pennylane.devices._qubit_device.QubitDevice.analytic_probability()

Return type:: ndarray

apply(operations, rotations=None)[source]¶

See pennylane.devices._qubit_device.QubitDevice.apply()

Return type:: None

capabilities()[source]¶

See pennylane.devices._qubit_device.QubitDevice.capabilities()

Return type:: dict[str, Any]

compile(circuit)[source]¶

Return type:: Circuit

generate_samples()[source]¶

See pennylane.devices._qubit_device.QubitDevice.generate_samples()

Return type:: ndarray

reset()[source]¶

Reset the backend state.

After the reset, the backend should be as if it was just constructed. Most importantly the quantum state is reset to its initial value.

Return type:: None

run(compiled_c)[source]¶

Run the compiled circuit, and query the result.

Return type:: None

pytket.extensions.pennylane.pennylane_convert.pennylane_to_tk(operations, wire_map, qreg, creg, measure=False)[source]¶

Convert a PennyLane circuit to a pytket circuit

Parameters:

operations (list[Operation]) – list of operations
wire_map (OrderedDict) – mapping of qubits
qreg (QubitRegister) – target qubit register
creg (BitRegister) – target bit register
measure (bool) – whether to add measurements

Return type:

Circuit

Returns:

pytket circuit

pytket.extensions.pennylane.pennylane_convert.apply_operations(operations, wire_map, qreg)[source]¶

Apply the circuit operations.

This method serves as an auxiliary method to apply().

Parameters:: operations (List[pennylane.operation.Operation]) – operations to be applied
Return type:: list[Circuit]
Returns:: A list of tket circuit objects that specify the corresponding operations
