Query: Overcoming resolution limits with quantum sensing   The field of quantum sensing explores the use of quantum phenomena to measure
a broad range of physical quantities, of both static and time-dependent types.
An important figure of merit for sensing time dependent signals is the spectral
resolution, i.e. the ability to resolve two different frequencies. Here we
study this problem, and develop new superresolution methods that rely on
quantum features. We first formulate a general criterion for superresolution in
quantum problems. Inspired by this, we show that quantum detectors can resolve
two frequencies from incoherent segments of the signal, irrespective of their
separation, in contrast to what is known about classical detection schemes. The
main idea behind these methods is to overcome the vanishing distinguishability
in resolution problems by nullifying the projection noise.
