Breaking Rayleigh's curse for two unbalanced single-photon emitters: BLESS technique
arXiv:2112.13244 · doi:10.1103/PhysRevApplied.23.024066
Abstract
Rayleigh's criterion states that resolving point sources below the point spread function width is impossible, with error increasing at shorter distances, known as Rayleigh's curse. While detection mode shaping solves this for equal sources, it fails for unbalanced sources with unknown brightness ratios. We propose BLESS, a technique using Beam moduLation and Examination of Shot Statistics, breaking Rayleigh's curse for unbalanced sources. Classical and quantum Cramer-Rao bound calculations show BLESS's strong potential for real imaging experiments.
