Bounding Kirkwood-Dirac negativity of Gaussian processes
Luca Bianchi, Carlo Marconi, Riccardo Cioli +1
The paper derives upper and lower bounds on the negativity of the Kirkwood‑Dirac quasiprobability for quantum states undergoing Gaussian processes, showing that Gaussian states can…
Bell state measurements in quantum optics: a review of recent progress and open challenges
Luca Bianchi, Carlo Marconi, Davide Bacco
Bell state measurements, which project bipartite qubit systems onto the maximally entangled Bell basis, are central to a wide range of quantum information processing tasks, includi…
Unified boson sampling
Luca Bianchi, Carlo Marconi, Laura Ares +2
Boson sampling is a key candidate for demonstrating quantum advantage, and has already yielded significant advances in quantum simulation, machine learning, and graph theory. In th…
Pre-detection squeezing as a resource for high-dimensional Bell-state measurements
Luca Bianchi, Carlo Marconi, Jan Sperling +1
Bell measurements, entailing the projection onto one of the Bell states, play a key role in quantum information and communication, where the outcome of a variety of protocols cruci…
Nonlinear protocol for high-dimensional quantum teleportation
Luca Bianchi, Carlo Marconi, Giulia Guarda +1
Bell measurements, which allow entanglement between uncorrelated distant particles, play a central role in quantum communication. Indeed sharing, measuring and creating entanglemen…
