mindquantum.algorithm.compiler.cz_decompose

mindquantum.algorithm.compiler.cz_decompose(gate: gates.ZGate)[source]

Decompose controlled ZGate gate.

Parameters: gate (ZGate) – a ZGate with one control qubits.
Returns: List[Circuit], all possible decompose solution.

Examples

>>> from mindquantum.algorithm.compiler import cz_decompose
>>> from mindquantum.core.circuit import Circuit
>>> from mindquantum.core.gates import Z
>>> cz = Z.on(1, 0)
>>> origin_circ = Circuit() + cz
>>> decomposed_circ = cz_decompose(cz)[0]
>>> origin_circ
