Abstract

We propose an optimal discrimination scheme for a case of four linearly independent nonorthogonal symmetric quantum states, based on linear optics only. The probability of discrimination is in agreement with the optimal probability for unambiguous discrimination among N symmetric states \[Phys. Lett. A 250, 223 (1998)\]. The experimental setup can be extended for the case of discrimination among 2^M nonorthogonal symmetric quantum states.
