Experimental scheme for unambiguous discrimination of linearly independent symmetric states
arXiv:0705.3813 · doi:10.1103/PhysRevA.76.062107
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 \textbf{250}, 223 (1998)]. The experimental setup can be extended for the case of discrimination among nonorthogonal symmetric quantum states.
