Resolving Mutually Coherent Bright Point-Sources
Ilya Karuseichyk, Giacomo Sorelli, Manuel Gessner +2
We analyze the problem of resolving two point-sources in the case of mutually coherent sources with arbitrary quantum statistics, mutual phase, relative and absolute intensity. We…
Moment-based superresolution: Formalism and applications
Giacomo Sorelli, Manuel Gessner, Mattia Walschaers +1
Sensitivity limits are usually determined using the Cramér-Rao bound. Recently this approach has been used to obtain the ultimate resolution limit for the estimation of the separat…
Quantification of Wigner Negativity Remotely Generated via Einstein-Podolsky-Rosen Steering
Yu Xiang, Shuheng Liu, Jiajie Guo +4
Wigner negativity, as a well-known indicator of nonclassicality, plays an essential role in quantum computing and simulation using continuous-variable systems. Recently, it has bee…
Non-Gaussian Quantum States and Where to Find Them
Mattia Walschaers
Gaussian states have played on important role in the physics of continuous-variable quantum systems. They are appealing for the experimental ease with which they can be produced, a…
Experimental statistical signature of many-body quantum interference
Taira Giordani, Fulvio Flamini, Matteo Pompili +8
Multi-particle interference is an essential ingredient for fundamental quantum mechanics phenomena and for quantum information processing to provide a computational advantage, as r…
Conditional preparation of non-Gaussian quantum optical states by mesoscopic measurement
Alexander O. C. Davis, Mattia Walschaers, Valentina Parigi +1
Non-Gaussian states of an optical field are important as a proposed resource in quantum information applications. While conditional preparation is a highly successful approach to p…
Maximal entanglement increase with single-photon subtraction
Kun Zhang, Jietai Jing, Nicolas Treps +1
Entanglement is an indispensable quantum resource for quantum information technology. In continuous-variable quantum optics, photon subtraction can increase the entanglement betwee…
Optimal observables and estimators for practical superresolution imaging
Giacomo Sorelli, Manuel Gessner, Mattia Walschaers +1
Recent works identified resolution limits for the distance between incoherent point sources. However, it remains unclear how to choose suitable observables and estimators to reach…
