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.…
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…
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…
Quantum second harmonic generation in terms of elementary processes
Giovanni Chesi
We address the quantum dynamics of second harmonic generation with a perturbative approach. By inspecting the Taylor expansion of the unitary evolution, we identify the subsequent…
