sf.physics.triples.amplifier_Abc

mrmustard.physics.triples.amplifier_Abc(g)[source]

The (A, b, c) triple of a tensor product of amplifiers.

The number of modes depends on the length of the input parameters.

Parameters:

g (Union[float, Iterable[float]]) – The values of the gains.

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 amplifier channels.

Raises:

ValueError – If g is smaller than 1.
