Experimental demonstration that SPADE with single-photon detectors achieves subdiffraction asymmetric source discrimination with lower error rates than direct imaging when crosstalk is below approximately 0.1.
This is compatible with a standard exoplanet detection scenario, in which the only prior knowledge on the system is the position of its centre [37]
