Current Research

We do theoretical research in the field of quantum physics and information. Our current areas of interest are:

  • Developing and applying criteria for certification of quantum devices.
  • Advancing our understanding of the interplay between information and thermodynamics.

We are also working on foundational topics arising from two decades of expertise in Bell nonlocality.


A non-classical state of the harmonic oscillator, detectable with a dynamics-based criterion [Ref 4].
