Sample space filling analysis for boson sampling validation
A. A. Mazanik, A. N. Rubtsov
Achieving a quantum computational advantage regime, and thus providing evidence against the extended Church-Turing thesis, remains one of the key challenges of modern science. Boso…
Intensity correlations in decoy-state BB84 quantum key distribution systems
Daniil Trefilov, Xoel Sixto, Víctor Zapatero +3
The decoy-state method is a prominent approach to enhance the performance of quantum key distribution (QKD) systems that operate with weak coherent laser sources. Due to the limite…
