Quantum-machine-learning channel discrimination. (arXiv:2206.09933v2 [quant-ph] UPDATED)

In the problem of quantum channel discrimination, one distinguishes between a
given number of quantum channels, which is done by sending an input state
through a channel and measuring the output state. This work studies
applications of variational quantum circuits and machine learning techniques
for discriminating such channels. In particular, we explore (i) the practical
implementation of embedding this task into the framework of variational quantum
computing, (ii) training a quantum classifier based on variational quantum
circuits, and (iii) applying …
