Autonomous Optical Alignment of Satellite-Based Entanglement Sources using Reinforcement Learning
Andrzej Gajewski, Robert Okuła, Marcin Pawłowski +1
Quantum entanglement distributed via satellites enable global-scale quantum communication. However, onboard sources are susceptible to misalignment due to dynamical orbital conditi…
The future of secure communications: device independence in quantum key distribution
Seyed Arash Ghoreishi, Giovanni Scala, Renato Renner +4
In the ever-evolving landscape of quantum cryptography, Device-independent Quantum Key Distribution (DI-QKD) stands out for its unique approach to ensuring security based not on th…
Quantum advantage for distributed computing without communication
L. Czekaj, M. Pawlowski, T. Vertesi +3
Understanding the role that quantum entanglement plays as a resource in various information processing tasks is one of the crucial goals of quantum information theory. Here we prop…
Quantum bidding in Bridge
S. Muhammad, A. Tavakoli, M. Kurant +3
Quantum methods allow to reduce communication complexity of some computational tasks, with several separated partners, beyond classical constraints. Nevertheless, experimental demo…
Activation of entanglement in teleportation
Ryszard Weinar, Wieslaw Laskowski, Marcin Pawlowski
We study the activation of entanglement in teleportation protocols. To this end, we a present derivation of the average fidelity of teleportation process with noisy classical chann…
Detection loophole attacks on semi-device-independent quantum and classical protocols
Michele Dall'Arno, Elsa Passaro, Rodrigo Gallego +2
Semi-device-independent quantum protocols realize information tasks - e.g. secure key distribution, random access coding, and randomness generation - in a scenario where no assumpt…
Hyperbits: the information quasiparticles
M. Pawlowski, A. Winter
Information theory has its particles, bits and qubits, just as physics has electrons and photons. However, in physics we have a special category of objects with no clear counterpar…
