Path-symmetric states and parity detection in quantum optical interferometry
In optical phase estimation, pure states that achieve maximal phase sensitivities with number counting, are symmetric with respect to a certain exchange of paths. We prove the optimality of photon-number parity detection for such path-symmetric states. © 2013 Optical Society of America.
