PhD positions – Optical atomic clocks and precision metrology

PhD positions – Optical atomic clocks and precision metrology

The Quantum Metrology group of Dr. Murray Barrett works on the development of an optical atomic clock with singly ionized lutetium and related precision measurement technologies.


The team is currently looking for talented and motivated researchers to fill several PhD positions. Successful applicants may start at the earliest possible opportunity.



  • A portable clock system: aimed at enabling optical clock technology to be used outside the laboratory and a first step towards practical application and commercialization
  • A chip scale optical clock utilizing CMOS technology with integrated laser addressing and detection:  aimed at establishing a scalable, manufacturable clock technology for future generations
  • A multi-ion clock: aimed at improving the stability of ion-based clocks, which are currently limited by single ion implementations 



Successful applicants would have an undergraduate degree showing a strong background in quantum physics.  Exceptional students with an engineering background may also be considered. Applications should include a CV, academic transcript, contact information for two referees, and a statement of their research interests.


Interested students should first contact Murray Barrett:
