Quantum Metrology Group

Our group has developed an optical atomic clock based on Lu+. Lutetium is a unique clock candidate in that it supports three clock transitions within the one atom enabling rigorous consistency checks on clock performance. We have shown that two of these transitions have very low systematic shifts making them competitive with the best systems in the world. In 2019 we demonstrated the feasibility of operating the clock with multiple ions which will enable improvements in measurement precision. More recently we demonstrated agreement between two clocks at the level of 10-18, which was limited by the measurement statistics and not systematic uncertainty. We are now investigating a microfabrication approach towards a more manufacturable and scalable ion-trap system for future clock implementations.

Job Description

We have a project that aims to provide a CMOS-based approach to ion trap implementation with the ultimate goal of providing an ion-trap with integrated photonic waveguides and detectors for laser addressing and state detection of ions. In this project the candidate will have a leadership role in the design and implementation of microfabricated ion-traps specifically tailored for the implementation of optical atomic clocks. It is expected that the candidate will work closely with local collaborators to capitalize on local microfabrication capabilities.

Job Requirements

  • PhD in experimental Physics/Engineering ideally with expertise in ion-traps and atomic physics.
  • Practical experience with microfabrication techniques is essential.
  • Fluency in written and spoken English.

The remuneration is competitive and depends on the expertise and skill set.
