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…
Demonstration of EPR steering using single-photon path entanglement and displacement-based detection
T. Guerreiro, F. Monteiro, A. Martin +15
We demonstrate the violation of an EPR steering inequality developed for single photon path entanglement with displacement-based detection. We use a high-rate source of heralded si…
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…
Narrowband Photon Pair Source for Quantum Networks
F. Monteiro, A. Martin, B. Sanguinetti +2
We demonstrate a compact photon pair source based on a periodically poled lithium niobate nonlinear crystal in a cavity. The cavity parameters are chosen such that the emitted phot…
An Energy Puzzle in Quantum Collapse
Thiago Guerreiro, Fernando Monteiro
Since its discovery, quantum theory has proven to be one of the most precise theories ever made. Measurement processes, however, do not seem to be governed by the unitary law of qu…
