mindquantum.algorithm.compiler.ch_decompose

mindquantum.algorithm.compiler.ch_decompose(gate: gates.HGate)[source]

Decompose controlled HGate gate.

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

Examples

>>> from mindquantum.algorithm.compiler import ch_decompose
>>> from mindquantum.core.circuit import Circuit
>>> from mindquantum.core.gates import T, X, H, S
>>> ch = H.on(1, 0)
>>> origin_circ = Circuit() + ch
>>> decomposed_circ = ch_decompose(ch)[0]
>>> origin_circ
