Postselection-loophole-free Bell test under strict spacetime constraints
Kannan Vijayadharan, Matías Rubén Bolaños, Andrea Pompermaier +5
Entanglement gives rise to correlations between distant quantum systems that cannot be explained by local realistic theories. Bell inequality violations provide a direct way to rev…
Multiplexing of Continuous-Variable and Discrete-Variable Quantum Key Distribution Systems over Fibered and Free-Space Channels
Mattia Sabatini, Edoardo Rossi, Matías R. Bolaños +7
Future quantum communication infrastructures will need to serve heterogeneous users on shared physical channels: short-range, high-throughput links favor Continuous-Variable Quantu…
Efficient Energy-Constrained Semi-Device-Independent QRNG with an Integrated Heterodyne Receiver
Mattia Sabatini, Carles Roch i Carceller, Tommaso Bertapelle +10
Semi-device-independent QRNG frameworks represent a particularly attractive approach, combining strong security guarantees with high randomness generation rates while relying only…
A Sagnac-based arbitrary time-bin state encoder for quantum communication applications
Kannan Vijayadharan, Matías Rubén Bolaños, Marco Avesani +3
Time-bin encoding of quantum information is highly advantageous for long-distance quantum communication protocols over optical fibres due to its inherent robustness in the channel…
Power-consumption Backdoor in Quantum Key Distribution
Beatriz Lopes da Costa, Matías R. Bolaños, Ricardo Chaves +7
Over the last decades, Quantum Key Distribution (QKD) has risen as a promising solution for secure communications. However, like all cryptographic protocols, QKD implementations ca…
