PhD Position

Quantum Computation Using Trapped Atoms

We are recruiting a PhD scholar to work on single- and multi-qubit gate operations using laser-cooled 87Rb atoms in optical tweezer arrays, including Rydberg excitation and entangling gate characterisation.

PhD Position

Yb Atomic Optical Clock

A position is available to work on the Ytterbium optical clock project, covering green MOT (556 nm) operation, narrow-line cooling, clock-transition spectroscopy, and optical frequency metrology.
