mindquantum.core.circuit.MixerAdder

class mindquantum.core.circuit.MixerAdder(adders: List[ChannelAdderBase], add_after=True)[source]

Execute each adder if all accepter and excluder are met.

Parameters

adders (List[BitFlipChannel]) – The adders you want to mix.
add_after (bool) – Whether add channel after quantum gate or not. If False, the channel will add before quantum gate. This add_after will override all`add_after` of sub adder. Default: True.

Examples

>>> from mindquantum.core.circuit import MeasureAccepter, BitFlipAdder, MixerAdder
>>> from mindquantum.core.circuit import Circuit
>>> circ = Circuit().rx('a', 0).h(0).measure_all()
>>> only_measure = MixerAdder([BitFlipAdder(0.1), MeasureAccepter()], add_after=False)
>>> only_measure(circ)
