Exploring the nature of gravity with quantum information methods
Bruna Sahdo, Natália Salomé Móller
The aim of this article is to provide an introduction to the use of quantum information methods for investigating the interface between quantum theory and gravity. To this end, we…
Subsystem entanglement and separability in quantum reference frames
T. Rick Perche, Natália Salomé Móller, Guilherme Franzmann
We find a necessary condition for subsystems to become entangled after a quantum reference frame transformation. We then distinguish between subsystems that admit separable descrip…
Quantum switch in the gravity of Earth
Natália S. Móller, Bruna Sahdo, Nelson Yokomizo
We introduce a protocol for a quantum switch in the gravitational field of a spherical mass and determine the time interval required for its realization in the gravity of Earth. On…
Shielding Property in Higher Dimensions
Natália S. Móller, Alberto L. de Paula, Cristhiano Duarte +1
When the reduced state of a many-body quantum system is independent of its remaining parts, we say it shows what has become known by shielding property. Under some assumptions, equ…
A Shielding Property for Thermal Equilibrium States on the Quantum Ising Model
Natália S. Móller, Alberto L. de Paula, Raphael C. Drumond
We show that Gibbs states of non-homogeneous transverse Ising chains satisfy a \emph{shielding} property. Namely, whatever the fields on each spin and exchange couplings between ne…
Bounding entanglement spreading after a local quench
Raphael C. Drumond, Natália S. Móller
We consider the variation of von Neumann entropy of subsystem reduced states of general many- body lattice spin systems due to local quantum quenches. We obtain Lieb-Robinson-like…
Quantum bounds on multiplayer linear games and device-independent witness of genuine tripartite entanglement
Gláucia Murta, Ravishankar Ramanathan, Natália Móller +1
Here we study multiplayer linear games, a natural generalization of XOR games to multiple outcomes. We generalize a recently proposed efficiently computable bound, in terms of the…
