Discrimination of dephasing channels
arXiv:2201.00388 · doi:10.1088/1751-8121/ac6d2c
Abstract
The problem of dephasing channel discrimination is addressed for finite-dimensional systems. In particular, the optimization with respect to input states without energy constraint is solved analytically for qubit, qutrit and ququart. Additionally, it is shown that resorting to side entanglement assisted strategy is completely useless in this case.
