Mattia WalschaersOur #Quantera project ApresSF produced a new result on distance estimation between #light sources. Generally speaking, spatial mode demultiplexing (#SPADE) offers a big advantage of the straighforward use of a camera. Here we show what happens when imperfections kick in and sources are not of equal brightness. SPADE is most advantageous when you detect few photons and when sources ar not too different.
Application range of crosstalk-affected spatial demultiplexing for resolving separations between unbalanced sources
Superresolution is one of the key issues at the crossroads of contemporary quantum optics and metrology. Recently, it was shown that for an idealized case of two balanced sources, spatial mode demultiplexing (SPADE) achieves resolution better than direct imaging even in the presence of measurement crosstalk [Phys. Rev. Lett. 125, 100501 (2020)]. In this work, we consider arbitrarily unbalanced sources and provide a systematic analysis of the impact of crosstalk on the resolution obtained from SPADE. As we dissect, in this generalized scenario, SPADE's effectiveness depends non-trivially on the strength of crosstalk, relative brightness and the separation between the sources. In particular, for any source imbalance, SPADE performs worse than ideal direct imaging in the asymptotic limit of vanishing source separations. Nonetheless, for realistic values of crosstalk strength, SPADE is still the superior method for several orders of magnitude of source separations.
