Honest-binding quantum bit commitment from separable operations
Ziad Chaoui, Anna Pappa, Matteo Rosati
Bit commitment is a fundamental cryptographic primitive and a cornerstone for numerous two-party cryptographic protocols, including zero-knowledge proofs. However, it has been prov…
Certification of Network Quantum Sensing
Matteo Rosati, Gabriele Bizzarri, Marco Barbieri
The distribution of quantum sensors on quantum networks is a key enabler of quantum technologies in interferometry, gravimetry, timekeeping, biological monitoring, and beyond. Yet,…
Private Remote Phase Estimation over a Lossy Quantum Channel
Farzad Kianvash, Marco Barbieri, Matteo Rosati
Private remote quantum sensing (PRQS) aims at estimating a parameter at a distant location by transmitting quantum states on an insecure quantum channel, limiting information leaka…
Controlling Sloppiness in Two-Phase Estimation with a Tunable Weak Measurement
Gabriele Bizzarri, Miranda Parisi, Mylenne Manrique +6
The description of complex systems requires a progressively larger number of parameters. However, in practice, it often happens that a small subset of parameters suffices to descri…
Photon-starved polarimetry via functional classical shadows
Matteo Rosati, Miranda Parisi, Linda Sansoni +3
Polarimetry and optical imaging techniques face challenges in photon-starved scenarios, where the low number of detected photons imposes a trade-off between image resolution, integ…
Faithful and secure distributed quantum sensing under general-coherent attacks
G. Bizzarri, M. Barbieri, M. Manrique +4
Quantum metrology and cryptography can be combined in a distributed and/or remote sensing setting, where distant end-users with limited quantum capabilities can employ quantum stat…
