Operational errors or decoherence effects are natural barriers to quantum computing implementations. In classical computation, errors can be corrected using redundancy. The translation to the quantum case is not immediate, due to the non-cloning theorem. Quantum error correcting codes were found, since the 1990s. Initially by suitable adaptations of classical error correcting codes. The s…
The connection between Bell nonlocality and quantum contextuality, two of the most intriguing features of quantum theory, has been subject of research since the first few decades after the establishment of these concepts. In recent years, generalizations of Bell scenarios which allow a nonlocality experiment to be performed concomitantly with a contextuality experiment have enabled new pe…
This project aims to introduce the student to research in Quantum Information Theory. For that, he will start studying Probability, Graph Theory and more advanced topics of Quantum Theory (usually not seen on undergraduate courses), allowing him to get in touch with one of the most recent developments in the state of the art of Quantum Theory: The colored graph approach for the study of q…
In this scientific initiation project it is proposed a study of contextually in quantum theory through a graph theoretic approach. In this way, part of the project is intended for learning some required aspects of graph theory, and for introducing some basic concepts of quantum mechanics. After being acquainted with the topics above, the project aims to investigate what is special in quan…
Contextuality is one of the features that distinguish quantum and classical theories. The incompatibility between non-contextual hidden-variable theories and quantum theory has been confirmed both theoretically and experimentally. More than nonlocality, this contradiction can be viewed as a contradiction of the structure of quantum theory with the intuition of classical theories, expres…

Bell nonlocality and quantum contextuality stand as two of the most instigating nonclassical phenomena in quantum theory. Notably, they have been shown to yield quantum advantages in a plethora of information processing tasks. Nonlocality, for example, can be used to establish secure cryptographic keys, while contextuality has a profound connection with promising models of quantum computa…
This project is associated to the PhD research project "Quantum Darwinism and Contextuality". The associated project aims to understand if non-contextuality emerges under usual classical limits of Quantum Theory. In particular, considering the paradigmatic case of decoherence and the modern program of Quantum Darwinism. This proposal of extension consists of studying classical limits in t…
