Universal construction of genuinely entangled subspaces of any size

Maciej Demianowicz

We put forward a simple construction of genuinely entangled subspaces -- subspaces supporting only genuinely multipartite entangled states -- of any permissible dimensionality for…

Simple sufficient condition for subspace to be completely or genuinely entangled

Maciej Demianowicz, Grzegorz Rajchel-Mieldzioć, Remigiusz Augusiak

We introduce a simple sufficient criterion, which allows one to tell whether a subspace of a bipartite or multipartite Hilbert space is entangled. The main ingredient of our criter…

Hybrid no-signaling-quantum correlations

Michał Banacki, Piotr Mironowicz, Ravishankar Ramanathan +1

Fundamental investigations in non-locality have shown that while the no-signaling principle alone is not sufficient to single out the set of quantum non-local correlations, local q…

Large violations in Kochen Specker contextuality and their applications

Ravishankar Ramanathan, Yuan Liu, Paweł Horodecki

The Kochen-Specker (KS) theorem is a fundamental result in quantum foundations that has spawned massive interest since its inception. We present state-independent non-contextuality…

Imitating quantum probabilities: Beyond Bell's theorem and Tsirelson bounds

Marek Czachor, Kamil Nalikowski

Local hidden-variable model of singlet-state correlations discussed in M. Czachor, Arithmetic loophole in Bell's Theorem: Overlooked threat to entangled-state quantum cryptography,…

Dynamical nonlocality in quantum time via modular operators

Ismael L. Paiva, Marcin Nowakowski, Eliahu Cohen

We formalize the concept of the modular energy operator within the Page and Wootters timeless framework. As a result, this operator is elevated to the same status as the more studi…

Probing the limits of quantum theory with quantum information at subnuclear scales

Michał Eckstein, Paweł Horodecki

Modern quantum engineering techniques enabled successful foundational tests of quantum mechanics. Yet, the universal validity of quantum postulates is an open question. Here we pro…
