Condensation dynamics in a two-dimensional photonic crystal waveguide

Autor: Efthymiou-Tsironi, Maria, Gianfrate, Antonio, Trypogeorgos, Dimitrios, Leblanc, Charly, Riminucci, Fabrizio, Salerno, Grazia, De Giorgi, Milena, Ballarini, Dario, Sanvitto, Daniele

Exciton-polariton condensation occurs at the extrema of the underlying dispersion where the density of states diverges and carriers can naturally accumulate. The existence of multiple such points leads to coupling and competition between the associat

GeV ALP from TeV Vector-like leptons

Autor: de Giorgi, Arturo, Zamoro, Marta Fuentes, Merlo, Luca

We present a model where a GeV axion-like-particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei-Quinn symmetry-breaking terms in an exotic leptonic sector. The latter provides a solution to the m

Quantum reservoir computing in atomic lattices

Autor: Llodrà, Guillem, Mujal, Pere, Zambrini, Roberta, Giorgi, Gian Luca

Quantum reservoir computing (QRC) exploits the dynamical properties of quantum systems to perform machine learning tasks. We demonstrate that optimal performance in QRC can be achieved without relying on disordered systems. Systems with all-to-all to

Quantum machine learning via continuous-variable cluster states and teleportation

Autor: García-Beni, Jorge, Paparelle, Iris, Parigi, Valentina, Giorgi, Gian Luca, Soriano, Miguel C., Zambrini, Roberta

A new approach suitable for distributed quantum machine learning and exhibiting memory is proposed for a photonic platform. This measurement-based quantum reservoir computing takes advantage of continuous variable cluster states as the main quantum r

Future cosmic microwave background (CMB) experiments are primarily targeting a detection of the primordial $B$-mode polarisation. The faintness of this signal requires exquisite control of systematic effects which may bias the measurements. In this w
