Description:
Author(s): Jaewoo Joo, Kimin Park, Hyunseok Jeong, William J. Munro, Kae Nemoto, and Timothy P. Spiller We investigate the phase enhancement of quantum states subject to nonlinear phase shifts. The optimal phase estimation of even entangled coherent states (ECSs) is shown to be better than that of NOON states with the same average particle number 〈 n 〉 and nonlinearity exponent k . We investigate the cre... [Phys. Rev. A 86, 043828] Published Thu Oct 18, 2012
