mindquantum.algorithm.compiler.cryy_decompose

mindquantum.algorithm.compiler.cryy_decompose(gate: gates.Ryy)

Decompose Ryy gate with control qubits.

Parameters

gate (Ryy) – a Ryy gate.

Returns

List[Circuit], all possible decompose solution.

Examples

>>> from mindquantum.algorithm.compiler import cryy_decompose
>>> from mindquantum.core.circuit import Circuit
>>> from mindquantum.core.gates import Ryy
>>> cryy = Ryy(2).on([0, 1], [2, 3])
>>> origin_circ = Circuit() + cryy
>>> decomposed_circ = cryy_decompose(cryy)[0]
>>> origin_circ
