Professor of Mathematical Physics, Faculty of Science



Ivette Fuentes is a Professor of Mathematical Physics at the University of Nottingham. From 2015-2018, she was Professor of Theoretical Quantum Optics at the University of Vienna and faculty member of the Vienna Doctoral Program on Complex Quantum Systems (CoQuS). She also held prestigious fellowships including a five year Career Acceleration Fellowship from the Engineering and Physical Sciences Research Council and an Alexander von Humboldt Fellowship for Experienced Researchers at the Technical University of Berlin, Germany. She obtained her PhD in 2003 from Imperial College supervised by P. L. Knight and V. Vedral working on quantum information and quantum optics. Her postdoctoral experience includes a fellowship at the Perimeter Institute for Theoretical Physics (Canada), a Glasstone Fellowship at the University of Oxford, and a Junior Research Fellowship at Mansfield College, Oxford. In 2017, she received an invitation to act as founding member and Director of the physics branch of the Roger Penrose Institute. Her research interests include a number of topics in mathematical physics including quantum information, quantum optics, quantum metrology, quantum communications and in particular, the overlap of these topics with relativity.

Expertise Summary

Ivette Fuentes pioneered research in the foundations of Relativistic Quantum Information, a field which deals with the theory and application of quantum information to answer questions in the overlap of quantum theory and relativity. Her early work deals with the study of entanglement in relativistic settings. Currently she works in the application of quantum metrology to quantum field theory in curved space-time (QFT-CS). This enables the estimation of proper times, lengths, accelerations and other space-time parameters. She has shown that quantum effects increase time dilation and that gravity affects entanglement and the measurement of time by quantum clocks. A critical limitation in understanding nature at regimes where quantum and relativistic effects co-exist is the lack of instruments to explore these scales. Ivette showed theoretically that space-time distortions produce observable changes in the quantum states of fields in Bose-Einstein Condensates (BEC). Using this effect, she proposed a low-cost table top quantum device that is capable of probing space-time effects directly. This could lead to a paradigm change in the detection of gravitational waves or probing dark energy. Ivette also introduced a novel quantum thermometer theory for non-demolition measurement of the temperature of a BEC. Her research also aims at deepening our understanding of the effects of relativity, including gravity and motion, in space-based quantum experiments and in applications such as quantum teleportation and cryptography. Experimentalists have verified her theoretical predictions for photon entanglement during source and detector free-fall, the generation of multipartite entanglement and quantum gates using relativistic motion and the effects of the vacuum field on geometric phases.

Research Summary

Relativistic quantum metrology and spacetime probes

We opened a new research direction by applying quantum metrology to quantum field theory in curved space-time (QFT-CS). This enables the estimation of proper times, lengths, accelerations and other space-time parameters. Using these techniques we have developed theoretically designs to measure gravitational waves, constrain dark energy models, search for dark matter and estimate spacetime parameters,
