Distributed quantum multiple-phase estimation using fewer photons
We show that by using N -photon two-mode polarization-entangled states and beam splitter networks, the Heisenberg scaling can be achieved in distributed quantum multiple-phase estimation, even with fewer photons than the number of phases.
