Dr Jesús Rubio

Postdoctoral Research Fellow


I am a theoretical physicist exploiting an information-theoretic view of fundamental physics to rationalise experimental data in realistic scenarios. This includes using stochastic thermodynamics theory to analyse data from sensors for single-molecule detection (Molecular Mechanics Initiative). Previously, I also looked at ways to enhance measurement schemes by exploiting the quantum properties of light and matter (quantum estimation and metrology). This perspective may inspire new paths for theory development and shed new light on our fundamental understanding of 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.

Research interests/areas I have worked in

  • Stochastic thermodynamics and non-equilibrium physics
  • Global quantum thermometry
  • Quantum information, estimation and metrology, including time and phase estimation, and both Bayesian and multiparameter approaches
  • Quantum foundations, including field theory
  • Data analysis with an information-theoretic aproach to probability theory

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