a general two-mode quantum pure state as a probe state，by using the Dirac symbol and the theory of
quantum representation transformation，we present a simple method to calculate the expectation value of parity operator
in the output state of a Mach-Zehnder interferometer.
Key words： parity measurement; MZI interferometer; Fock state; Dirac symbol
