Cuantres.0: Quantum Technologies 3.0

Carlos Sabín is a researcher in Theoretical Physics. After receiving his PhD at the end of 2011 from the Complutense University of Madrid and having a brief post-doctoral experience at CSIC, he moved to the University of Nottingham (UK) in mid-2012, where he was a researcher and assistant professor. His research area ranges from Quantum Technologies (Quantum Information and Computation, Quantum Simulations, Quantum Metrology) to Quantum Field Theory, and his approach combines an interest in theoretical foundations with a concern for proposing workable experiments in the laboratory. He is currently focused on the analysis of the Dynamical Casimir Effect and other relativistic phenomena from the point of view of Quantum Technology. ComFuturo Researcher (I edition) at the Institute of Fundamental Physics of the CSIC, where he developed his project “Quantum Technologies 3.0“.

Project Summary

This project aims to launch the development of a new generation of quantum technologies that incorporate relativistic phenomena, such as particle creation, specifically in Quantum Information, Quantum Computing, and Quantum Metrology devices.

It is usually assumed that relativistic effects are negligible in these systems, being therefore possible to describe them within non-relativistic Quantum Mechanics. However, gravity and accelerated motion have effects on quantum properties that are observable with current technology.

It is essential to begin considering these effects properly. For this, we need Quantum Field Theory in curved space-time. This will allow quantum technologies to develop beyond the regimes in which quantum mechanics is a good approximation of Field Theory.

A thorough understanding of relativistic effects in quantum properties will allow us not only to make the necessary corrections in the technologies it affects but will also pave the way for developing new technologies that use these effects as a resource.

For example, entanglement generated through relativistic motion will be used as a resource in Quantum Information and Quantum Computing tasks and to improve the accuracy of measuring devices.


New quantum technologies promise to revolutionise our information society. Computers, for example, will be able to perform calculations now impossible and there will be ways to produce cryptographic keys that no one will be able to hack. This project aims to explore ways to further improve such technologies by using physical systems and phenomena that have not been considered until now.
