mindquantum.algorithm.compiler.crxx_decompose

mindquantum.algorithm.compiler.crxx_decompose(gate: gates.Rxx)

Decompose Rxx gate with control qubits.

Parameters

gate (Rxx) – a Rxx gate.

Returns

List[Circuit], all possible decompose solution.

Examples

>>> from mindquantum.algorithm.compiler.decompose import crxx_decompose
>>> from mindquantum.core import Circuit, Rxx
>>> crxx = Rxx(2).on([0, 1], [2, 3])
>>> origin_circ = Circuit() + crxx
>>> decomposed_circ = crxx_decompose(crxx)[0]
>>> origin_circ
