qiskit.quantum_info.decompose_clifford

decompose_clifford(clifford, method=None)

DEPRECATED: 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].

Obsoleto desde la versión 0.23.0: The function qiskit.quantum_info.synthesis.clifford_decompose.decompose_clifford() is deprecated as of qiskit-terra 0.23.0. It will be removed no earlier than 3 months after the release date. Instead, use the function qiskit.synthesis.synth_clifford_full.

Parámetros

• clifford (Clifford) – a clifford operator.

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