mindquantum.algorithm.compiler.ct_decompose

mindquantum.algorithm.compiler.ct_decompose(gate: gates.TGate)[source]

Decompose controlled TGate gate.

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

Examples

>>> from mindquantum.algorithm.compiler import ct_decompose
>>> from mindquantum.core.circuit import Circuit
>>> from mindquantum.core.gates import T
>>> ct = T.on(1, 0)
>>> origin_circ = Circuit() + ct
>>> decomposed_circ = ct_decompose(ct)[0]
>>> origin_circ
