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



News

  • Sep 2018: Our lab, together with many consortium members, 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 Dr Josh Nunn from the University of Bath. Very best wishes for your research guys!

  • May 2018: Our paper "Displacemon electromechanics: how to detect quantum interference in a nanomechanical resonator" has now been published in Phys. Rev. X. Many congratulations Kiran, Natalia, and Edward! We're looking forward to continuing our collaboration!

  • May 2018: Michael has been awarded Australia's National Measurement Institute Prize for his "outstanding contributions to precision measurement in the emerging new field of cavity quantum optomechanics"! The NMI Prize is awarded annually on the 20th of May—world metrology day—which celebrates the 1875 metre convention.

  • May 2018: Our paper "Generation of mechanical interference fringes by multi-photon counting" has now been published in New Journal of Physics. Our work made the first experimental observation of mechanical interference fringes and theoretically proposes how to generate Schrodinger cat states of mechanical motion by projection onto optical NOON states. Many congratulations Martin, Till, Lewis and Andrew—our collaborators from the quantum technology lab in Brisbane!

  • Apr 2018: Dr Heng Shen has been awarded a Royal Society Newton International Fellowship and joins our team after completing his PhD and postdoc in the Polzik and Blatt groups, respectively. Huanying Heng!

  • Apr 2018: Dr Kiran Khosla joins our team for his first post-doc after completing his PhD in the Milburn group in Brisbane. Welcome aboard Kiran!

  • Mar 2018: Paulo Sahium joins our team as a visiting undergraduate. Bem-vindo Paulo!

  • Jan 2018: Jack Clarke is awarded an EPSRC scholarship, after his MPhys at the University of Oxford, and continues with our team for his PhD at Imperial! Congratulations Jack - it's great to have you aboard!
