Abstract: We propose an optimal discrimination scheme for a case of four linearlyindependent nonorthogonal symmetric quantum states, based on linear opticsonly. The probability of discrimination is in agreement with the optimalprobability for unambiguous discrimination among N symmetric states Phys.Lett. A \textbf{250}, 223 (1998). The experimental setup can be extended forthe case of discrimination among $2^M$ nonorthogonal symmetric quantum states.
