Integrated quantum photonics

The goal of the project is to understand new physical phenomena arising from quantum and nonlinear optical integration. In the future this research may open doors to new types of computers and simulators with information capacity exceeding the number of elementary particles in the entire universe.

Beam matching using machine learning

This project aims to use a machine learning algorithm to perform beam alignment in an optics experiment. It would involve mode-matching two optical beams using motorised mirror mounts. Additional degrees of freedom like lens positions and beam polarisation can be added later.

Optical quantum memory

An optical quantum memory will capture a pulse of light, store it and then controllably release it. This has to be done without ever knowing what you have stored, because a measurement will collapse the quantum state. We are exploring a "photon echo" process to achieve this goal.

Atomic magnetometer for exploring physics beyond the standard model and gyroscopy

Atomic sensors are exquisitely sensitive. We aim to model and build a new generation of atomic sensors to measure magnetic fields, rotation and dark matter.

Machine learning for optics and controls

Optical cavities are widely used in physics and precision measurement.  This project will explore the use of modern machine learning methods for the control of suspended optical cavities.

Quantum super resolution

When two point sources of light are close together, we just see one blurry patch. This project aims to use coherent measurement techniques in quantum optics to measure the separation between the point sources beyond the Rayleigh's limit.

Miniature absolute gravimeter for long-term gravity surveys

Absolute gravimeters tie their measurement of gravity to the definition of the second 
by interrogating the position of a falling test mass using a laser interferometer. Our vision is to develop and prototype a miniaturised absolute gravimeter by 
leveraging modern vacuum, laser, and micro-electromechanical systems.
