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 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.…
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^*…
Quantum Key Distribution with Basis-Dependent Detection Probability
Federico Grasselli, Giovanni Chesi, Nathan Walk +7
Quantum Key Distribution (QKD) is a promising technology for secure communication. Nevertheless, QKD is still treated with caution in certain contexts due to potential gaps between…
