A general approach to physical realization of unambiguous quantum-state discrimination
arXiv:quant-ph/0603058 · doi:10.1016/j.physleta.2006.03.076
Abstract
We present a general scheme to realize the POVMs for the unambiguous discrimination of quantum states. For any set of pure states it enables us to set up a feasible linear optical circuit to perform their optimal discrimination, if they are prepared as single-photon states. An example of unknown states discrimination is discussed as the illustration of the general scheme.
