A unified framework for anomalous boson bunching
Léo Pioge, Leonardo Novo, Nicolas J. Cerf
Anomalous bunching is a paradoxical quantum interferometric phenomenon in which partially distinguishable photons exhibit a higher probability of bunching into two or more modes th…
Higher-order covariance matrices for non-Gaussian quantum states
VojtÄch Kala, Petr Marek, Nicolas J. Cerf
The paper introduces higher-order covariance matrices built from quadrature monomials to characterize non‑Gaussian continuous‑variable quantum states, showing how they transform un…
Majorization precursors to supermodularity and subadditivity on the majorization lattice
Alexander Stévins, Michael G. Jabbour, Serge Deside +1
We establish two structural majorization relations, which we call precursors, underlying the properties of supermodularity and subadditivity on the lattice induced by majorization.…
Complementarity between bosonic and fermionic many-body interferences with partially distinguishable particles
Marco Robbio, Michael G. Jabbour, Nicolas J. Cerf
It is well known that bosons and fermions exhibit opposite behaviors when experiencing interference, in the sense that bosons have a tendency to bunch whereas fermions have a tende…
Symmetry-driven thermalization via finite de Finetti theorems
Uttam Singh, Nicolas J. Cerf
Thermal behavior in subsystems of closed quantum systems is commonly attributed to dynamical chaos, quantum ergodicity, canonical typicality, or the eigenstate thermalization hypot…
Wigner entropy conjecture and the interference formula in quantum phase space
Zacharie Van Herstraeten, Nicolas J. Cerf
Wigner-positive quantum states have the peculiarity to admit a Wigner function that is a genuine probability distribution over phase space. The Shannon differential entropy of the…
