Quantum computing for accelerating cross-correlations intensive applications in signal processing
Valentina Caprara Vivoli, Yuchen Deng, Kohr Holger +1
Despite their importance as subfields of mathematics and engineering, signal and image processing have not received much attention in the field of quantum computation. Cross-correl…
High fidelity GHZ generation within nearby nodes
Valentina Caprara Vivoli, Jérémy Ribeiro, Stephanie Wehner
Generating entanglement in a distributed scenario is a fundamental task for implementing the quantum network of the future. We here report a protocol that uses only linear optics f…
Thorough evaluation of GHZ generation protocols using conference key agreement
Valentina Caprara Vivoli
The generation of GHZ states in quantum networks is a key element for the realization of several quantum information tasks. Given the complexity of the implementation of such gener…
Parameter regimes for a single sequential quantum repeater
Filip Rozpędek, Kenneth Goodenough, Jérémy Ribeiro +6
Quantum key distribution allows for the generation of a secret key between distant parties connected by a quantum channel such as optical fibre or free space. Unfortunately, the ra…
Heralded Amplification of Path Entangled Quantum States
F. Monteiro, E. Verbanis, V. Caprara Vivoli +4
Device-independent quantum key distribution (DI-QKD) represents one of the most fascinating challenges in quantum communication, exploiting concepts of fundamental physics, namely…
What does it take to see entanglement?
Valentina Caprara Vivoli, Pavel Sekatski, Nicolas Sangouard
Tremendous progress has been realized in quantum optics for engineering and detecting the quantum properties of light. Today, photon pairs are routinely created in entangled states…
Optomechanical Bell test
V. Caprara Vivoli, T. Barnea, C. Galland +1
Photons of a laser beam driving the upper motional sideband of an optomechanical cavity can decay into photon-phonon pairs by means of an optomechanical parametric process. The pho…
Revealing Genuine Optical-Path Entanglement
F. Monteiro, V. Caprara Vivoli, T. Guerreiro +5
How can one detect entanglement between multiple optical paths sharing a single photon? We address this question by proposing a scalable protocol, which only uses local measurement…
Comparing different approaches for generating random numbers device-independently using a photon pair source
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +6
What is the most efficient way to generate random numbers device-independently using a photon pair source based on spontaneous parametric down conversion (SPDC)? We consider this q…
Challenging preconceptions about Bell tests with photon pairs
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +7
Motivated by very recent experiments, we consider a scenario "à la Bell" in which two protagonists test the Clauser-Horne-Shimony-Holt (CHSH) inequality using a photon-pair source…
High-bandwidth quantum memory protocol for storing single photons in rare-earth doped crystals
Valentina Caprara Vivoli, Nicolas Sangouard, Mikael Afzelius +1
We present a detailed analysis of a high-bandwidth quantum memory protocol for storing single photons in a rare-earth-ion doped crystal. The basic idea is to benefit from a coheren…
