We study a noisy order of quantum channels called the degraded order,
which shows that one channel is a degraded version of the other channel.
An efficient algorithm is proposed to decide the degraded order of two
quantum channels, based on the steepest descent method to minimize a
cost function represented by the Choi matrix. Using the proposed
algorithm, we show a numerical study of the relation between the
degraded order and the quantum mutual information. |
