mrmustard.physics.fock.ket_to_dm(ket)[source]

Maps a ket to a density matrix.

Parameters:

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

Returns:

the density matrix

Return type:

Tensor
