mindquantum.algorithm.compiler.crz_decompose

mindquantum.algorithm.compiler.crz_decompose(gate: gates.RZ)

Decompose controlled RZ gate.

Parameters

gate (RZ) – a RZ gate with one control qubits.

Returns

List[Circuit], all possible decompose solution.

Examples

>>> from mindquantum.algorithm.compiler import crz_decompose
>>> from mindquantum.core.circuit import Circuit
>>> from mindquantum.core.gates import X, RZ
>>> crz = RZ(1).on(1, 0)
>>> origin_circ = Circuit() + crz
>>> decomposed_circ = crz_decompose(crz)[0]
>>> origin_circ
