- decompose_clifford(clifford, method=None)¶
Decompose a Clifford operator into a QuantumCircuit.
For N <= 3 qubits this is based on optimal CX cost decomposition from reference . For N > 3 qubits this is done using the general non-optimal greedy compilation routine from reference , which typically yields better CX cost compared to the AG method in .
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.
