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…
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…
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…
Response of quantum spin networks to attacks
Bhuvanesh Sundar, Mattia Walschaers, Valentina Parigi +1
We investigate the ground states of spin models defined on networks that we imprint (e.g. non-complex random networks like Erdos-Renyi or complex networks like Watts-Strogatz, and…
