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…

Quantum bounds and device-independent security with rank-one qubit measurements
Lorenzo Coccia, Matteo Padovan, Andrea Pompermaier +5
Device-independent (DI) quantum protocols exploit Bell inequality violations to ensure security or certify quantum properties without making assumptions about the internal workings…
