Quantum random-number generator with non-demolition measurements: semi-device-independent implementation
Paolo Solinas, Giovanni Chesi
The paper proposes a quantum random-number generator that uses a tripartite system with non‑demolition measurements, allowing simultaneous randomness generation and quantum certifi…
High-dimensional quantum key distribution rates for multiple measurement bases
Nikolai Wyderka, Giovanni Chesi, Hermann Kampermann +2
We investigate the advantages of high-dimensional encoding for a quantum key distribution protocol. In particular, we address a BBM92-like protocol where the dimension of the syste…
Quantum Uncertainty and Entropy
Giovanni Chesi, Lorenzo Maccone
We review the plethora of uncertainty relations that appear in quantum mechanics and their nuances. We present both foundational applications, e.g. in understanding and defining co…
Complementarity-based complementarity: the choice of mutually unbiased observables shapes quantum uncertainty relations
Laura Serino, Giovanni Chesi, Benjamin Brecht +3
Quantum uncertainty relations impose fundamental limits on the joint knowledge that can be acquired from complementary observables: perfect knowledge of a quantum state in one basi…
Experimental entropic uncertainty relations in dimensions three to five
Laura Serino, Giovanni Chesi, Benjamin Brecht +3
We provide experimental validation of tight entropic uncertainty relations for the Shannon entropies of observables with mutually unbiased eigenstates in high dimensions. In partic…
High-dimensional quantum key distribution with resource-efficient detection
Maciej Ogrodnik, Adam Widomski, Dagmar Bruà +7
While quantum key distribution (QKD) based on two-dimensional (qubit) encoding is a mature, field-tested technology, its performance is lacking for many cryptographic applications.…
