qml.devices.default_qubit

The default.qubit device is PennyLane’s standard qubit-based device.

Classes

DefaultQubit([wires, shots, seed, max_workers])

A PennyLane device written in Python and capable of backpropagation derivatives.

Functions

accepted_analytic_measurement(m)	Specifies whether a measurement is accepted when analytic.
accepted_sample_measurement(m)	Specifies whether a measurement is accepted when sampling.
adjoint_observables(obs)	Specifies whether or not an observable is compatible with adjoint differentiation on DefaultQubit.
adjoint_ops(op)	Specify whether or not an Operator is supported by adjoint differentiation.
adjoint_state_measurements(tape[, device_vjp])	Perform adjoint measurement preprocessing.
all_state_postprocessing(results, ...)	Process a state measurement back into the original measurements.
no_counts(tape)	Throws an error on counts measurements.
null_postprocessing(results)	An empty post-processing function.
observable_accepts_analytic(obs[, is_expval])	Verifies whether an observable supports analytic measurement
observable_accepts_sampling(obs)	Verifies whether an observable supports sample measurement
stopping_condition(op)	Specify whether or not an Operator object is supported by the device.
stopping_condition_shots(op)	Specify whether or not an Operator object is supported by the device with shots.
