Quantum random-number generator with non-demolition measurements: semi-device-independent implementation
Paolo Solinas, Giovanni Chesi
We propose and analyze a novel quantum random-number generator based on a tripartite quantum system in which two subsystems act as detectors. Within a quantum non-demolition measur…
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…
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…
Bosonic two-stroke heat engines with polynomial nonlinear coupling
Giovanni Chesi, Chiara Macchiavello, Massimiliano Federico Sacchi
We study the thermodynamics of two-stroke heat engines where two bosonic modes and are coupled by the general nonlinear interaction $V_θ = \exp {(θa^{\dagger n}b^m -θ^* a^n…
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…
High-dimensional quantum key distribution with resource-efficient detection
Maciej Ogrodnik, Adam Widomski, Dagmar Bruß +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.…
