Making Non-Markovian master equations accessible with approximate environments

Gerardo Suárez, Michał Horodecki

Accurate and efficient simulation of open quantum systems remains a significant challenge, particularly for Non-Markovian dynamics. We demonstrate the profound utility of expressin…

Efficient multi port-based teleportation schemes

Michał Studziński, Marek Mozrzymas, Piotr Kopszak +1

In this manuscript we analyse generalised port-based teleportation (PBT) schemes, allowing for transmitting more than one unknown quantum state (or a composite quantum state) in on…

Practical No-Signalling proof Randomness Amplification using Hardy paradoxes and its experimental implementation

Ravishankar Ramanathan, Michał Horodecki, Hammad Anwer +6

Device-Independent (DI) security is the best form of quantum cryptography, providing information-theoretic security based on the very laws of nature. In its highest form, security…

Gadget structures in proofs of the Kochen-Specker theorem

Ravishankar Ramanathan, Monika Rosicka, Karol Horodecki +3

The Kochen-Specker theorem is a fundamental result in quantum foundations that has spawned massive interest since its inception. We show that within every Kochen-Specker graph, the…

Amplifying the randomness of weak sources correlated with devices

Hanna Wojewodka, Fernando G. S. L. Brandao, Andrzej Grudka +6

The problem of device-independent randomness amplification against no-signaling adversaries has so far been studied under the assumption that the weak source of randomness is uncor…

Linear game non-contextuality and Bell inequalities - a graph-theoretic approach

Piotr Gnaciński, Monika Rosicka, Ravishankar Ramanathan +4

We study the classical and quantum values of one- and two-party linear games, an important class of unique games that generalizes the well-known XOR games to the case of non-binary…
