Dr Jesús Rubio

Postdoctoral Research Fellow


I am a theoretical physicist working at the intersection of fundamental physics and probability theory. My current aim is to find out what different quantum technologies, together with the language of quantum estimation theory, can teach us about the general principles governing nature. 

I joined the Quantum Non-equilibrium group at the University of Exeter in October 2019, after having defended my thesis Non-asymptotic quantum metrology: extracting maximum information from limited data on 18 September 2019 at the University of Sussex. For more information, see my biography

Areas I work/have worked in

  • Quantum estimation, metrology and interferometry (time, phase, multiparameter problems, Bayesian techniques, etc)
  • Global quantum thermometry, stochastic thermodynamics and non-equilibrium physics
  • Quantum uncertainty relations and correlations
  • Mechanics, in all its forms (analytical, quantum, statistical, stochastic, etc)
  • Logic-based probability theory for data analysis

A complete list of my publications and preprints is available via my ORCID iD: 0000-0002-8193-8273
