Measurements allow us to interrogate nature. Progress in the foundations of physics thus demands a theory of measurements suitable for regimes where fundamental physics comes into play. To this end, I am developing the theory of a universally applicable framework for quantum metrology and estimation. Relevant themes include:

Quantum science and foundations

  • Quantum metrology in exotic regimes
  • Quantum inference à la Bayes, with a particular emphasis on variational principles, multiparameter estimation, uncertainty relations, and fluctuation theorems
  • Quantum light, thermodynamics, and relativity

Quantum information technologies

  • Principles of quantum sensing with applications in interferometry, thermometry, imaging, and general-purpose networks of sensors
  • Physics-inspired data science, quantum and beyond
