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…
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…
Entanglement of truncated quantum states
Giacomo Sorelli, Vyacheslav N. Shatokhin, Filippus S. Roux +1
We investigate the impact of Hilbert-space truncation upon the entanglement of an initially maximally entangled bipartite quantum state, after propagation under an enta…
Universal entanglement losses induced by angular uncertainty
Giacomo Sorelli, Vyacheslav N. Shatokhin, Andreas Buchleitner
We study the diffraction of two maximally entangled qubits encoded into spatial modes of light with orbital angular momenta , on angular apertures. Exploiting the un…
Entanglement protection of high-dimensional states by adaptive optics
Giacomo Sorelli, Nina Leonhard, Vyacheslav N. Shatokhin +2
We study the potential of adaptive optics (AO) to protect entanglement of high-dimensional photonic orbital-angular-momentum (OAM) states against turbulence-induced phase distortio…
Protecting entanglement of twisted photons by adaptive optics
Nina Leonhard, Giacomo Sorelli, Vyacheslav N. Shatokhin +2
We study the efficiency of adaptive optics (AO) correction for the free-space propagation of entangled photonic orbital-angular-momentum (OAM) qubit states, to reverse moderate atm…
