OVERCOMING THE “RAYLEIGH CATASTROPHE” USING ASYMMETRIC ANTENNAS
Abstract
We investigate the possibilities of quantum radars the radiating antennas of which consist of two interacting quantum dipoles in coherent or thermal states. It is shown that such asymmetric antennas allow us not only to reach super-resolution but also to overcome the “Rayleigh catastrophe”. In the case of a coherent antenna, an intensity measurement is sufficient to achieve these effects. In the thermal case, it is necessary to measure the temporal correlations of the field.
