Wright's conjecture on phase retrieval by position, Fourier, and unitary measurements
Wright's conjecture on phase retrieval by position, Fourier, and unitary measurements
Let be the Hilbert space of square-integrable functions, let denote the Fourier transform, and let
A tuple of measurement operators does phase retrieval if its associated measurement data determine a state up to the relevant phase equivalence. Wright's conjecture. There exists a unitary operator such that does phase retrieval. This extends Pauli's phase-retrieval question by asking whether one additional unitary measurement, besides the identity and Fourier transform, suffices. The source attributes the conjecture to R. Wright and states that it remains open.
