  Title Resolving mutually-coherent point sources of light with arbitrary statistics Type Journal Article
  Year 2022 Publication Physical Review Research Abbreviated Journal Phys. Rev. Res.  
  Volume 4 Issue 4 Pages 043010 - 11pp  
  Keywords  
  Abstract We analyze the problem of resolving two mutually coherent point sources with arbitrary quantum statistics, mutual phase, and relative and absolute intensity. We use a sensitivity measure based on the method of moments and compare direct imaging with spatial-mode demultiplexing (SPADE), analytically proving advantage of the latter. We show that the moment-based sensitivity of SPADE saturates the quantum Fisher information for all known cases, even for non-Gaussian states of the sources.
