Metropolitan entanglement distribution between an atom and a near-visible photon
Maya Büki, Pooja Malik, Florian Fertig +9
Entanglement distribution is the overarching purpose of quantum networks. While communication over long distances can use deployed fiber infrastructure, it requires photons in the…
No-cost Bell nonlocality certification from quantum tomography and its applications in quantum-magic-resource witnessing
Pawel Cieslinski, Lukas Knips, Harald Weinfurter +1
Tomographic measurements are the standard tool for characterizing quantum states, yet they are usually regarded only as means for state reconstruction or fidelity measurement. Here…
Unmasking the Polygamous Nature of Quantum Nonlocality
Paweł Cieśliński, Lukas Knips, Mateusz Kowalczyk +4
Quantum mechanics imposes limits on the statistics of certain observables. Perhaps the most famous example is the uncertainty principle. Similar trade-offs also exist for the simul…
Deep-Learning-Based Radio-Frequency Side-Channel Attack on Quantum Key Distribution
Adomas Baliuka, Markus Stöcker, Michael Auer +3
Quantum key distribution (QKD) protocols are proven secure based on fundamental physical laws, however, the proofs consider a well-defined setting and encoding of the sent quantum…
