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…

GHz-rate all-fiber active polarization state analyzer for quantum protocols
Andrea Pompermaier, Kannan Vijayadharan, Costantino Agnesi +3
Active selection of the measurement basis underpins quantum protocols including device-independent quantum key distribution, quantum teleportation with active feed-forward, and Bel…

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…
