Bell inequalities for device-independent protocols ﻿
Salavrakos, Alexia (Universitat Politècnica de Catalunya, 2019-03-26)
The technological era that we live in is sometimes described as the Information Age. Colossal amounts of data are generated every day and considerable effort is put into creating technologies to process, store and transmit ...
Bounding Hilbert Space dimension from Temporal Correlations ﻿
Gallego López, Rodrigo (Universitat Politècnica de Catalunya, 2009-09-09)
In this work, we tackle the problem of assessing the Hilbert space dimension from the set of correlations obtained when measuring in a nonlocal black box scheme. The concept of a dimension witness and its recent applications ...
Certification of many-body systems ﻿
Baccari, Flavio (Universitat Politècnica de Catalunya, 2019-05-17)
Quantum physics is arguably both the most successful and the most counterintuitive physical theory of all times. Its extremely accurate predictions on the behaviour of microscopic particles have led to unprecedented ...
Device-independent certification of quantum resources ﻿
Supic, Ivan (Universitat Politècnica de Catalunya, 2018-09-19)
The last two decades have been a very fruitful period for the fundamental research related to quantum information theory. Today we have a fairly good understanding of how intrinsically quantum properties affect various ...

Entanglement in the graph-state formalism ﻿
Dhara, Chrirag (Universitat Politècnica de Catalunya, 2009-09-09)
We investigate the decoherence dynamics of a class of multi-particle entangled states - graph states - when subjected to individual noise processes. Recent analytical results for Pauli noise channels are summarized here. ...

Hierarchical representations in machine learning and many-body quantum physics ﻿
Blázquez García, Raúl (Universitat Politècnica de Catalunya, 2017-10-27)
Over the past few years a number of proofs have emerged revealing the many connections between the methods used in quantum-many body physics and those in machine learning. In particular, much attention has been given to ...
Impact of imperfections on correlation-based quantum information protocols ﻿
Passaro, Elsa (Universitat Politècnica de Catalunya, 2016-05-30)
Quantum information science is a rapidly evolving field both from the theoretical and the experimental viewpoint, motivated by the fact that protocols exploiting quantum resources can perform tasks that are unfeasible in ...
Information-theoretical Secret-key agreement and Bound information ﻿
Kreissig, Martin (Universitat Politècnica de Catalunya, 2009-02-25)
One big problem of the communication between two parties is the secrecy. That means how much information a third party can obtain by intercepting the messages transmitted from one honest party to the other one. Therefore ...
Intrinsic randomness in non-local theories: quantification and amplification ﻿
Dhara, Chirag (Universitat Politècnica de Catalunya, 2013-06-12)
Quantum mechanics was developed as a response to the inadequacy of classical physics in explaining certain physical phenomena. While it has proved immensely successful, it also presents several features that severely ...

Mathematical and Technological Aspects of Quantum Information Processing ﻿
Tura i Brugués, Jordi (Universitat Politècnica de Catalunya, 2011-03)
Since its genesis, quantum mechanics has proved to be a very accurate model for predicting the behavior of the world below the nanoscale. However, crucial breakthroughs in technology were needed in order to be able to e ...
