Experimental realization of a generalized measuring device via a one-dimensional photonic quantum walk

Bian, Zhihao, Zhang, Rong, Qin, Hao et al.

Understand

We demonstrate an implementation of unambiguous state discrimination of two equally probable single-qubit states via a one-dimensional photonic quantum walk experimentally.

  • Furthermore we experimentally realize a quantum walk algorithm for implementing a generalized measurement in terms of positive operator value measurement on a single qubit.
  • The measurement of the single-photons' positions corresponds to a measurement of an element of the positive operator value measurement on the polarizations of the single-photons.
