FastCNOTUnitObjective¶

class FastCNOTUnitObjective(num_qubits, cnots)[Quellcode]¶

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

Parameter

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

Methods Defined Here

`gradient`	Computes the gradient of objective function.
`objective`	Computes the objective function and some intermediate data for the subsequent gradient computation.

Attributes

num_cnots¶: Returns: A number of CNOT units to be used by the approximate circuit.

num_thetas¶: Returns: Number of parameters (angles) of rotation gates in this circuit.
