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…
Finite-size resource scaling for learning quantum phase transitions with fidelity-based support vector machines
Aaqib Ali, Giovanni Scala, Cosmo Lupo +1
Quantum kernels offer a valid procedure for learning quantum phase transitions on quantum processing devices, yet issues on the scalability of the learning strategy in connection w…
Self-testing tilted strategies for maximal loophole-free nonlocality
Nicolas Gigena, Ekta Panwar, Giovanni Scala +3
The degree of experimentally attainable nonlocality, as gauged by the loophole-free or effective violation of Bell inequalities, remains severely limited due to inefficient detecto…
