mrmustard.physics.triples.attenuator_kraus_Abc(eta)

The entire family of Kraus operators of the attenuator (loss) channel as a single (A, b, c) triple. The last index is the “bond” index which should be summed/integrated over.

Parameters:

eta (float) – The value of the transmissivity.

Return type:

Union[ndarray[Tuple[int, int], Union[TypeVar(R, float16, float32, float64), TypeVar(C, complex64, complex128), TypeVar(Z, int16, int32, int64), TypeVar(N, uint16, uint32, uint64)]], ndarray[Tuple[int], Union[TypeVar(R, float16, float32, float64), TypeVar(C, complex64, complex128), TypeVar(Z, int16, int32, int64), TypeVar(N, uint16, uint32, uint64)]], TypeVar(R, float16, float32, float64), TypeVar(C, complex64, complex128), TypeVar(Z, int16, int32, int64), TypeVar(N, uint16, uint32, uint64)]

Returns:

The (A, b, c) triple of the kraus operators of the attenuator (loss) channel.
