Trapped atomic ions are the basis of the world’s most advanced quantum computers. We trap the ions in an ultra-high vacuum chamber using electric fields and control them with laser beams.

My research interests focus on the fabrication of integrated optical devices for quantum information applications. In particular we have a facility for the fabrication of miniaturised optical circuits in lithium niobate. Our devices can be used for realisation of integrated quantum circuits as well as for the realisation of classical optical sensors.
Our lab focuses on two main projects:
- Building miniature optics into the trap structure, using integrated circuit technology. These optics act as high-resolution microscopes to image the ions. They enabled us to obtain the world’s first image of the shadow of a single atom.
- Controlling ions with ultrafast laser pulses. By using laser pulses of picosecond (10-12 s) duration, we plan to exert extremely strong forces on ions. These strong forces can be used to increase the clock rate of quantum computers by a hundredfold.
