qiskit.synthesis.synth_clifford_greedy

synth_clifford_greedy(clifford)

Decompose a Clifford operator into a QuantumCircuit based on the greedy Clifford compiler that is described in Appendix A of Bravyi, Hu, Maslov and Shaydulin.

This method typically yields better CX cost compared to the Aaronson-Gottesma method.

Parameters

clifford (Clifford) -- a clifford operator.

Returns

a circuit implementation of the Clifford.

Return type

QuantumCircuit

Raises

QiskitError -- if symplectic Gaussian elimination fails.
