High-quality entangled photon source by symmetric beam displacement design
Giacomo Paganini, Alvaro Cuevas, Robin Camphausen +2
Entangled photon sources (EPSs) are pivotal in advancing quantum communication, computing and sensing. The demand for deploying efficient, robust EPSs in the field, characterized b…
A quantum-enhanced wide-field phase imager
Robin Camphausen, Álvaro Cuevas, Luc Duempelmann +7
Quantum techniques can be used to enhance the signal-to-noise ratio in optical imaging. Leveraging the latest advances in single photon avalanche diode array cameras and multi-phot…
Experimental Lower Bounds to the Classical Capacity of Quantum Channels
Mario A. Ciampini, Álvaro Cuevas, Paolo Mataloni +2
We show an experimental procedure to certify the classical capacity for noisy qubit channels. The method makes use of a fixed bipartite entangled state, where the system qubit is s…
Experimental investigation of superdiffusion via coherent disordered Quantum Walks
Andrea Geraldi, Alessandro Laneve, Luis Diego Bonavena +6
Many disordered systems show a superdiffusive dynamics, intermediate between the diffusive one, typical of a classical stochastic process, and the so called ballistic behaviour, wh…
A Novel Bulk-Optics Scheme for Quantum Walk with High Phase Stability
Andrea Geraldi, Luís Diego Bonavena, Carlo Liorni +2
A novel bulk optics scheme for quantum walks is presented. It consists of a one-dimensional lattice built on two concatenated displaced Sagnac interferometers that make it possible…
All-optical implementation of collision-based evolutions of open quantum systems
Álvaro Cuevas, Andrea Geraldi, Carlo Liorni +5
We present a new optical scheme enabling the implementation of highly stable and configurable non-Markovian dynamics. Here one photon qubit can circulate in a multipass bulk geomet…
Experimental detection of quantum channel capacities
Álvaro Cuevas, Massimiliano Proietti, Mario Arnolfo Ciampini +4
We present an effcient experimental procedure that certifies non vanishing quantum capacities for qubit noisy channels. Our method is based on the use of a fixed bipartite entangle…
Entangling one polariton with a photon: effect of interactions on a single-polariton quantum state
Álvaro Cuevas, Blanca Silva, Juan Camilo López Carreño +16
Polaritons are quasi-particles originating from the coupling of light with matter that demonstrated quantum phenomena at the many-particle mesoscopic level, such as BEC and superfl…
Cut-and-paste restoration of entanglement transmission
Alvaro Cuevas, Andrea Mari, Antonella De Pasquale +5
The distribution of entangled quantum systems among two or more nodes of a network is a key task at the basis of quantum communication, quantum computation and quantum cryptography…
Experimental observation of weak non-Markovianity
Nadja K. Bernardes, Alvaro Cuevas, Adeline Orieux +4
Non-Markovianity has recently attracted large interest due to significant advances in its characterization and its exploitation for quantum information processing. However, up to n…
Postselection-Loophole-Free Bell Test Over an Installed Optical Fiber Network
Gonzalo Carvacho, Jaime Cariñe, Gabriel Saavedra +9
Device-independent (DI) quantum communication will require a loophole-free violation of Bell inequalities. In typical scenarios where line-of-sight between the communicating partie…
Long-distance distribution of genuine energy-time entanglement
A. Cuevas, G. Carvacho, G. Saavedra +7
Any practical realization of entanglement-based quantum communication must be intrinsically secure and able to span long distances avoiding the need of a straight line between the…
