FastCNOTUnitObjective

class qiskit.synthesis.unitary.aqc.FastCNOTUnitObjective(num_qubits, cnots)

Implementation of objective function and gradient calculator, which is similar to DefaultCNOTUnitObjective but several times faster.

Parameters

num_qubits (int) – number of qubits.
cnots (ndarray) – a CNOT structure to be used in the optimization procedure.

Methods

gradient(param_values)

Computes the gradient of objective function. See description of the base class method.

Parameters

param_values (ndarray) –

Return type

ndarray

objective(param_values)

Computes the objective function and some intermediate data for the subsequent gradient computation. See description of the base class method.

Parameters

param_values (ndarray) –

Return type

float
