The quantum-mechanical parity operator enables the reconstruction of the phase space representation of a quantum state [1,2,3,4]. However, the implementation of the parity operation is a subtle issue.
In this poster, we reveal the intrinsic relation between the parity operator and the quantum-mechanical harmonic oscillator. In particular, we present two methods for its realization: (i) we rely on a continuous time evolution in a harmonic potential, and (ii) we employ a combination of pulsed harmonic potentials and free propagation.
By exploiting these methods, we construct a novel parity interferometer. The output of our device measures the parity of a given initial state.
