    "abstract": "We investigate the dependence of the fidelity of a Mach-Zehnder quantum\ninterferometer on the prior information about the phase, for Fock state input\nand for maximally entangled (N00N) state input. For no prior information, the\nfidelity for Fock state input is greater than for N00N state input. In the\nlimit of a narrow distribution describing the prior information, we find that\nboth Fock and N00N state inputs lead to nearly equal fidelity.",
