Josep Batle Vallespir
Assistant Professor (Professor Ajudant Doctor)
Josep did his M.S. Physics at the Universitat de les Illes Balears, where he also obtained his Ph.D. degree in Physics. Upon completion of his PhD, with the thesis entitled “Characterization of Quantum Entangled States and Information Measures” download, and under the supervision of the late Montserrat Casas, he had to leave academia and pursue a career as civil servant in 2005. During several years he has been teaching mathematics at high school, whilst carrying out freelance research, before coming back to research and lecturing at different universities (he taught many courses on quantum mechanics and quantum information from 2007 to 2012 at the Physics Department at the UIB as “Professor Associat”, and at a private American university in Kuwait from 2013 to 2015). He had participated in over five research projects before 2013. He has been shortlisted and/or declined offers in several Middle East and South American institutions. Currently he is assistant professor at the Universitat de les Illes Balears.
Josep’s primary source of interest is quantum information and quantum sensing, although he has interests in BEC, solitons and discrete mathematics.
Quantum information science is devoted to unraveling the fundamental principles of quantum mechanics—entanglement, nonlocality, and coherence—to harness their power for computation, communication, and sensing. It bridges abstract theory with transformative applications, from secure cryptographic protocols to quantum-enhanced measurements and simulations of complex systems. Aligned with this vision, Josep’s work pursues a multifaceted exploration of:
- Quantum correlations and entanglement
- Foundational and device-independent tests
- Quantum algorithms and sensing
- Quantum communication and security
- Classical-quantum interfaces
The last years have been actively devoted to employ public quantum computer platforms for research, such as IBM Quantum, IQM or IonQ. Josep has worked thoroughly with a research group based in Warsaw, Poland. The design and implementations of quantum mechanics tests and sensing witnesses has been the driven force of his latest publications.
