Monogamy of entanglement between cones
Guillaume Aubrun, Alexander Müller-Hermes, Martin Plávala
A separable quantum state shared between parties and can be symmetrically extended to a quantum state shared between party and parties for every $k\in…
All incompatible measurements on qubits lead to multiparticle Bell nonlocality
Martin Plávala, Otfried Gühne, Marco Túlio Quintino
Bell nonlocality is a fundamental phenomenon of quantum physics as well as an essential resource for various tasks in quantum information processing. It is known that for the obser…
Newton's laws of motion generating gravity-mediated entanglement
Marta Maria Marchese, Martin Plávala, Matthias Kleinmann +1
The interface between quantum theory and gravity represents still uncharted territory. Recently, some works suggested promising alternative approaches aimed at witnessing quantum f…
Symmetries and Wigner representations of operational theories
Ties-A. Ohst, Martin Plávala
We develop the theory of Wigner representations for general probabilistic theories (GPTs), a large class of operational theories that include both classical and quantum theory. The…
Entangled vs. Separable Choice
Nail Kashaev, Martin Plávala, Martin Plávala +1
A judge observes the joint probabilistic choice rule of two decision makers: the frequency of action pairs across pairs of local covariates. The rule is separable if behavior can b…
Simple Information Processing Tasks with Unbounded Quantum Advantage
Teiko Heinosaari, Oskari Kerppo, Leevi Leppäjärvi +1
Communication scenarios between two parties can be implemented by first encoding messages into some states of a physical system which acts as the physical medium of the communicati…
