Recovery-Free CHSH Nonlocality with Particle Loss
Giovanni Scala, Cosmo Lupo
Can CHSH nonlocality survive particle loss without applying an explicit recovery operation? In principle, any deterministic recovery can be absorbed into the measurement. Operation…

Third-Order Local Randomized Measurements for Finite-size Entanglement Certification
Giovanni Scala, Gniewomir Sarbicki
Randomized measurements access nonlinear functionals without full tomography, yet turning third-order local single-copy data into a strong entanglement test remains difficult. We c…

Preprocessing noise in finite-size quantum key distribution
Gabriele Staffieri, Giuseppe D'Ambruoso, Giovanni Scala +1
It is known that preprocessing noise may boost quantum key distribution by expanding the range of values of tolerated noise. For BB84, adding trusted noise may allow the generation…
