In our recent work we consider the estimation of the separation of two incoherent point sources when prior knowledge on the separation is given. We compute the Minimum Mean Squared Error and the behavior of Direct Detection and SPADE. Our work can be found on arXiv. Update: Our work has been accepted to APL Quantum.

Our paper has been recently published in Physical Review Applied. Emily Van Milligen (Wyant College of Optical Sciences, Univ. of Arizona), first author of our paper, wrote the following popular summary: Quantum networks have the potential to distribute entangled qubit pairs, typically photons, across vast distances, enabling breakthroughs in areas like long-baseline astronomy and distributed

We work on one of the most well-known and important quantum sensing paradigms, that of sensing an optical phase. However, we consider the largely overlooked Bayesian approach. The literature on optical phase sensing in the frequentist approach (i.e., Fisher information approach) is vast, proving retrospectively the importance of said problem. In our work, we examine
