Non-classicality tests and entanglement witnesses for macroscopic mechanical superposition states
Oleg Gittsovich, Tobias Moroder, Ali Asadian +2
We describe a set of measurement protocols for performing non-classicality tests and the verification of entangled superposition states of macroscopic continuous variable systems,…
Steering maps and their application to dimension-bounded steering
Tobias Moroder, Oleg Gittsovich, Marcus Huber +2
The existence of quantum correlations that allow one party to steer the quantum state of another party is a counterintuitive quantum effect that has been described already at the b…
Could Gaussian regenerative stations act as quantum repeaters?
Ryo Namiki, Oleg Gittsovich, Saikat Guha +1
Higher transmission loss diminishes the performance of optical communication|be it the rate at which classical or quantum data can be sent reliably, or the secure key generation ra…
Steering bound entangled states: A counterexample to the stronger Peres conjecture
Tobias Moroder, Oleg Gittsovich, Marcus Huber +1
Quantum correlations are at the heart of many applications in quantum information science and, at the same time, they form the basis for discussions about genuine quantum effects a…
Squashing model for detectors and applications to quantum key distribution protocols
Oleg Gittsovich, Normand J. Beaudry, Varun Narasimhachar +3
We develop a framework that allows a description of measurements in Hilbert spaces that are smaller than their natural representation. This description, which we call a "squashing…
Role of correlations in the two-body-marginal problem
Lin Chen, Oleg Gittsovich, Kavan Modi +1
Quantum properties of correlations have a key role in disparate fields of physics, from quantum information processing, to quantum foundations, to strongly correlated systems. We t…
