Abstract:

We investigate the dependence of the fidelity of a Mach-Zehnder quantum interferometer on the prior information about the phase, for Fock state input and for maximally entangled N00N state input. For no prior information, the fidelity for Fock state input is greater than for N00N state input. In the limit of a narrow dis- tribution describing the prior information, we find that both Fock and N00N state inputs lead to nearly equal fidelity.
