Optimal interferometric certification of multi-photon indistinguishability
Marco Robbio, Michał Oszmaniec, Nicolas J. Cerf +2
Multiphoton indistinguishability is a key resource for photonic quantum technologies, yet its characterization typically relies on resource-intensive methods. In this work, we deve…
Wigner-positive quantum states can have lower entropy than the vacuum
Zacharie Van Herstraeten, Nicolas J. Cerf, Ulysse Chabaud
The Wigner entropy conjecture posits that pure Gaussian states minimize the Shannon entropy of non-negative Wigner functions, known as the Wigner entropy. We show that mixing a spe…
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
Vojtěch Kala, Petr Marek, Nicolas J. Cerf
Covariance matrices lie at the heart of the powerful and well-established symplectic framework for describing continuous-variable Gaussian quantum states. However, since this frame…
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…
