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…
Error Mitigation in Bosonic Systems via Virtual Distillation
Leonardo Finocchiaro, Marco Robbio, Diogo Gomes +5
Virtual distillation is a promising error-mitigation technique that exploits multiple copies of a noisy quantum state to estimate observables as if measured on a purified state. Al…
Native linear-optical protocol for efficient multivariate trace estimation
Leonardo Novo, Marco Robbio, Ernesto F. Galvão +1
The Hong-Ou-Mandel test estimates the overlap between spectral functions characterizing the internal degrees of freedom of two single photons. It can be viewed as a photon-native p…
Limits of multimode bunching for boson sampling validation: anomalous bunching induced by time delays
Léo Pioge, Leonardo Novo, Nicolas J. Cerf
The multimode bunching probability is expected to provide a useful criterion for validating boson sampling experiments. Its applicability, however, is challenged by the existence o…
Complexity of Gaussian quantum optics with a limited number of non-linearities
Michael G. Jabbour, Leonardo Novo
It is well known in quantum optics that any process involving the preparation of a multimode gaussian state, followed by a gaussian operation and gaussian measurements, can be effi…
A logical implication between two conjectures on matrix permanents
Léo Pioge, Kamil K. Pietrasz, Benoit Seron +2
We prove a logical implication between two old conjectures stated by Bapat and Sunder about the permanent of positive semidefinite matrices. Although Drury has recently disproved b…
