mindquantum.algorithm.compiler.crx_decompose

mindquantum.algorithm.compiler.crx_decompose(gate: gates.RX)[source]

Decompose controlled RX gate.

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

Examples

>>> from mindquantum.algorithm.compiler import crx_decompose
>>> from mindquantum.core.circuit import Circuit
>>> from mindquantum.core.gates import RX
>>> crx = RX(1).on(1, 0)
>>> origin_circ = Circuit() + crx
>>> decomposed_circ = crx_decompose(crx)[0]
>>> origin_circ
