Quantum enhanced estimation of diffusion
Dominic Branford, Christos N. Gagatsos, Jai Grover +2
Momentum diffusion is a possible mechanism for driving macroscopic quantum systems towards classical behaviour. Experimental tests of this hypothesis rely on a precise estimation o…
Tempering Rayleigh's curse with PSF shaping
M. Paur, B. Stoklasa, J. Grover +4
It has been argued that, for a spatially invariant imaging system, the information one can gain about the separation of two incoherent point sources decays quadratically to zero wi…
Optimal measurements for quantum spatial superresolution
J. Rehacek, Z. Hradil, D. Koutny +3
We construct optimal measurements, achieving the ultimate precision predicted by quantum theory, for the simultaneous estimation of centroid, separation, and relative intensities o…
Multiparameter Quantum Metrology of Incoherent Point Sources: Towards Realistic Superresolution
J. Rehacek, Z. Hradil, B. Stoklasa +4
We establish the multiparameter quantum Cramér-Rao bound for simultaneously estimating the centroid, the separation, and the relative intensities of two incoherent optical point so…
