mindquantum.core.circuit.SequentialAdder

class mindquantum.core.circuit.SequentialAdder(adders: List[ChannelAdderBase])[源代码]

依次执行每一个添加器。

参数：

adders (List[ChannelAdderBase]) - 想要执行的 adder 。

样例：

>>> from mindquantum.core.circuit import SequentialAdder, MixerAdder, BitFlipAdder, NoiseChannelAdder
>>> from mindquantum.core.circuit import MeasureAccepter, ReverseAdder, NoiseChannelAdder, Circuit
>>> from mindquantum.core.circuit import NoiseExcluder
>>> from mindquantum.core.gates import DepolarizingChannel
>>> circ = Circuit().h(0).x(1, 0).measure_all()
>>> circ
