Correlations and signaling in the Schrödinger-Newton model
Jacek Aleksander Gruca, Ankit Kumar, Ray Ganardi +3
The Schrödinger--Newton model is a semi-classical theory in which, in addition to mutual attraction, massive quantum particles interact with their own gravitational fields. While t…
Quantitative non-classicality of mediated interactions
Ray Ganardi, Ekta Panwar, Mahasweta Pandit +2
In plethora of physical situations one can distinguish a mediator -- a system that couples other, non-interacting systems. Often the mediator itself is not directly accessible to e…
Generalised Uncertainty Relations from Finite-Accuracy Measurements
Matthew J. Lake, Marek Miller, Ray Ganardi +1
In this short note we show how the Generalised Uncertainty Principle (GUP) and the Extended Uncertainty Principle (EUP), two of the most common generalised uncertainty relations pr…
Hierarchy of correlation quantifiers comparable to negativity
Ray Ganardi, Marek Miller, Tomasz Paterek +1
Quantum systems generally exhibit different kinds of correlations. In order to compare them on equal footing, one uses the so-called distance-based approach where different types o…
Cooperation and dependencies in multipartite systems
Waldemar Klobus, Marek Miller, Mahasweta Pandit +7
We propose an information-theoretic quantifier for the advantage gained from cooperation that captures the degree of dependency between subsystems of a global system. The quantifie…
Generalised uncertainty relations from superpositions of geometries
Matthew J. Lake, Marek Miller, Ray F. Ganardi +3
Phenomenological approaches to quantum gravity implement a minimum resolvable length-scale but do not link it to an underlying formalism describing geometric superpositions. Here,…
Entanglement gain in measurements with unknown results
Margherita Zuppardo, Ray Ganardi, Marek Miller +2
We characterise non-selective global projective measurements capable of increasing quantum entanglement between two particles. We show that non-selective global projective measurem…
Detecting non-decomposability of time evolution via extreme gain of correlations
Tanjung Krisnanda, Ray Ganardi, Su-Yong Lee +2
Non-commutativity is one of the most elementary non-classical features of quantum observables. Here we propose a method to detect non-commutativity of interaction Hamiltonians of t…
