decompose_clifford(clifford, method=None)[ソース]

Decompose a Clifford operator into a QuantumCircuit.

For N <= 3 qubits this is based on optimal CX cost decomposition from reference [1]. For N > 3 qubits this is done using the general non-optimal greedy compilation routine from reference [3], which typically yields better CX cost compared to the AG method in [2].

パラメータ
• clifford (Clifford) – a clifford operator.

• method (str) – Optional, a synthesis method (『AG』 or 『greedy』). If set this overrides optimal decomposition for N <=3 qubits.

a circuit implementation of the Clifford.
