toqito.channel_ops.natural_representation

Kraus operators to natural representation.

Module Contents

toqito.channel_ops.natural_representation.natural_representation(kraus_ops)

Convert a set of Kraus operators to the natural representation of a quantum channel.

The natural representation of a quantum channel is given by: (Phi = sum_i K_i otimes K_i^*) where (K_i^*) is the complex conjugate of (K_i).

Examples

`python exec="1" source="above" import numpy as np from toqito.channel_ops import natural_representation k0 = np.sqrt(1/2) * np.array([[1, 0], [0, 1]]) k1 = np.sqrt(1/2) * np.array([[0, 1], [1, 0]]) print(natural_representation([k0, k1])) `

Parameters:

kraus_ops (list[numpy.ndarray])

Return type:

numpy.ndarray
