Quantum Science and Technology
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.

Superconducting and spin qubits are leading quantum computing technologies, but we currently have no way to connect them to optical quantum networks that will make up a future quantum internet. This project will develop an interconnect capable of efficiently converting microwave quantum information from these qubits to optical frequencies.

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.

The idea of equilibration is ubiquitous throughout nature. Out-of-equilibrium dynamics – be it caused by a disturbance and subsequent “rethermalisation”, or by passing through a phase transition – is a difficult question to characterise. This project looks at both equilibration and phase transitions in a Bose-Einstein condensate of metastable helium atoms.

This project combines theoretical and experimental research on exciton polaritons in semiconductor microcavities. We investigate emergent quantum phenomena far from equilibrium and their applications for next-generation optoelectronics devices.

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.

The Global Network of Optical Magnetometers for Exotic Physics (GNOME) uses precision atomic magnetometers to look new physics. The concept is to have a global network of magnetometers looking for correlated magnetic field fluctuations that may be caused by strange, and unknown physics.

This project will construct a 3D optical lattice apparatus for ultracold metastable Helium atoms, which will form an experimental quantum-simulator to investigate quantum many-body physics. A range of experiments will be performed such as studying higher order quantum correlations across the superfluid to Mott insulator phase transition.

This project goal is to investigate, theoretically and experimentally, photonic systems with synthetic dimensionality exceeding the three spatial dimensions, and reveal new opportunities for applications in optical signal switching and sensing in classical and quantum photonics.

Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project will investigate how antimatter and matter interact by experimentally studying the interaction of positrons (the electron anti-particle) with trapped ultracold rubidium atoms.

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.

This project aims to engineer diamond quantum computers and communication networks.

This project aims for developing polarization optical devices based on all-dielectric metasurfaces. As no bulky optical elements and moving parts are required, these devices are compact, stable, and can operate in a single-shot mode with high time resolution. Potential applications include sensitive biological imaging and quantum state manipulation and tomography.

This project aims to be the first in the world to use radiation pressure force of laser beams to levitate a macroscopic mirror. The coherence of this resonantly amplified scheme creates a unique opto-mechanical environment for precision quantum metrology and tests of new physics theories.
