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…
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…
Systematic derivation of Tsirelson bounds in arbitrary dimensions
Lorenzo Coccia, Matteo Padovan, Giuseppe Vallone
The study of Bell nonlocality and the bounds of quantum correlations, the so-called Tsirelson bounds, is fundamental to quantum information science and the exploration of the limit…
Gigahertz-rate thin-film lithium niobate receiver for time-bin quantum communication
Andrea Bernardi, Marco Clementi, Marcello Bacchi +12
Time-bin encoded quantum states of light are crucial for quantum technology applications. The integration of manipulation functionalities into chip-scale devices is essential for d…
A time-to-digital converter with steady calibration through single-photon detection
MatÃas Rubén Bolaños, Daniele Vogrig, Paolo Villoresi +2
Time-to-Digital Converters (TDCs) are a crucial tool in a wide array of fields, in particular for quantum communication, where time taggers performance can severely affect the qual…
