Universal linear manipulation via routing and projective measurements
Alessio Baldazzi, Sonia Mazzucchi, Lorenzo Pavesi
Multiport interferometers with ports are basic devices in both classical and quantum photonics. Ideally, they implement a linear unitary transformation between the input and ou…

A resource-efficient and noise-robust entanglement witness based on the swap test
Sebastiano Guaraldo, Sonia Mazzucchi, Alessio Baldazzi +2
Quantum entanglement is an essential resource for quantum technologies, and the controlled swap test provides a versatile tool for its detection and quantification. Here, we propos…

Feynman path integrals on compact Lie groups with bi-invariant Riemannian metrics
Nicoló Drago, Sonia Mazzucchi, Valter Moretti
In this work we consider a suitable generalization of the Feynman path integral on a specific class of Riemannian manifolds consisting of compact Lie groups with bi-invariant Riema…
