Our #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.
