Uranium concentrations in groundwater in a localized area of a site exceed the USEPA Maximum Contaminant Level (MCL) by a factor of one thousand. Although the groundwater seepage velocity ranges up… Expand

Separability of diagonal symmetric states: a quadratic conic optimization problem

- Jordi Tura i Brugués, A. Aloy, R. Quesada, M. Lewenstein, A. Sanpera
- Mathematics
- 28 June 2017

We study the separability problem in mixtures of Dicke states i.e., the separability of the so-called Diagonal Symmetric (DS) states. First, we show that separability in the case of DS in $C^d\otimes… Expand

Device-Independent Witnesses of Entanglement Depth from Two-Body Correlators.

Bell correlation depth in many-body systems

- F. Baccari, Jordi Tura i Brugués,

- 27 February 2018

We address the question of assessing the number of particles sharing genuinely nonlocal correlations in a multipartite system. While the interest in multipartite nonlocality has grown in recent… Expand

The quantum marginal problem for symmetric states: applications to variational optimization, nonlocality and self-testing

- A. Aloy, M. Fadel, Jordi Tura i Brugués
- PhysicsNew Journal of Physics
- 13 January 2020

In this paper, we present a method to solve the quantum marginal problem for symmetric d-level systems. The method is built upon an efficient semi-definite program that uses the compatibility… Expand

Entangled symmetric states and copositive matrices

- Carlo Marconi, A. Aloy, Jordi Tura i Brugués, A. Sanpera
- PhysicsQuantum
- 11 December 2020

Entanglement in symmetric quantum states and the theory of copositive matrices are intimately related concepts. For the simplest symmetric states, i.e., the diagonal symmetric (DS) states, it has… Expand

Storage capacity and learning capability of quantum neural networks

- M. Lewenstein, A. Gratsea, Andreu Riera-Campeny, A. Aloy, V. Kasper, A. Sanpera
- Computer ScienceQuantum Science and Technology
- 11 November 2020

We study the storage capacity of quantum neural networks (QNNs), described by completely positive trace preserving (CPTP) maps acting on an N-dimensional Hilbert space. We demonstrate that attractor… Expand
