DefaultCNOTUnitObjective

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

A naive implementation of the objective function based on CNOT units.

Parameters

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

Methods

gradient(param_values)

Computes a gradient with respect to parameters given a vector of parameter values.

Parameters

param_values (ndarray) – a vector of parameter values for the optimization problem.

Returns

an array of gradient values.

Return type

ndarray

objective(param_values)

Computes a value of the objective function given a vector of parameter values.

Parameters

param_values (ndarray) – a vector of parameter values for the optimization problem.

Returns

a float value of the objective function.

Return type

SupportsFloat
