mindquantum.core.circuit.NoiseExcluder

class mindquantum.core.circuit.NoiseExcluder(add_after=True)[源代码]

排除噪声门。

参数：

add_after (bool) - 在量子门前面或者后面添加量子信道。默认值： True。

样例：

>>> from mindquantum.core.circuit import Circuit, NoiseExcluder, BitFlipAdder, MixerAdder
>>> from mindquantum.core.gates import DepolarizingChannel
>>> circ = Circuit().x(0)
>>> circ += DepolarizingChannel(0.1).on(0)
>>> circ
