Welcome to the Quantum Measurement Lab!

We pursue a combination of experimental and theoretical research to develop powerful new quantum technologies and explore the foundations of physics. Our current research interests include:

  • quantum optomechanics
  • quantum photonics
  • hybrid quantum systems
  • quantum sensing
  • the quantum-to-classical transition
  • the interface of quantum mechanics and gravity

  • Jan 2019: Our paper "Observation of Brillouin optomechanical strong coupling with an 11 GHz mechanical mode", has now been published in Optica! This experiment is the first to report Brillouin optomechanical strong coupling to high frequency phonons. Many congratulations Georg and Magda, and our collaborators at the National Physical Laboratory!

  • Nov 2018: Together with our local collaborator Steve Kolthammer, we have been awarded an EPSRC-funded Early-Career Capital Grant to purchase some ultra-high-efficiency superconducting single photon counters!

  • Oct 2018: Andreas Svela and Niall Moroney have completed their MSc degrees! Many congratulations Andreas and Niall and all the very best with your PhD research ahead!

  • Sep 2018: Our lab, together with many researchers across the UK, has been awarded an STFC staging proposal "Quantum Sensors for Fundamental Physics"!

  • Sep 2018: Our paper "Growing macroscopic superposition states via cavity quantum optomechanics", has now been published in Quantum Science and Technology! Many congratulations Jack on your excellent first paper!

  • Aug 2018: Lars Freisem joins our team for his PhD. Herzlich willkommen Lars!

  • Jul 2018: Niall Moroney, John Price, and Andreas Svela join our team as MSc + PhD students! Welcome aboard Niall and John! Velkommen Andreas! Niall, John, and Andreas are part of the Quantum Systems Engineering Skills and Training Hub. Niall and Andreas will work closely with our collaborators in the Microphotonics Research Laboratory, NPL, Teddington and John will work closely with our collaborator Josh Nunn from the University of Bath. Very best wishes for your research guys!
