Beating the classical resolution limit via multi-photon interferences of independent light sources
S. Oppel, Th. Büttner, Pieter Kok, Joachim von Zanthier · Research in Optical Sciences · 2012
We discuss multi-photon interferences up to fifth order between indistinguishable photons emitted by independent light sources. For certain detector positions we observe an interference pattern which beats the classical resolution limit.
