mindquantum.core.circuit.as_ansatz

mindquantum.core.circuit.as_ansatz(circuit_fn)

Conversion decorator of a circuit to an ansatz circuit.

Parameters

circuit_fn (Union[Circuit, FunctionType, MethodType]) – A Circuit or a callable function that can return a Circuit.

Returns

Function, if circuit_fn is a callable function that will return a Circuit. Circuit, if circuit_fn is already a Circuit.

Examples

>>> from mindquantum.core.circuit import as_ansatz, Circuit
>>> from mindquantum.core.gates import RX
>>> @as_ansatz
... def create_circuit():
...     circ = Circuit()
...     circ += RX('a').on(0)
...     return circ
>>> circ = create_circuit()
>>> circ.ansatz_params_name
['a']
>>> circ.as_encoder()
>>> circ.ansatz_params_name
[]
>>> circ = as_ansatz(circ)
>>> circ.ansatz_params_name
['a']
