Non-equilibrium quantum condensation of microcavity exciton polaritons

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.

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.

Mass-entangled ultracold helium atoms

This experimental project aims to create entangled states of ultracold helium atoms where the entanglement is between atoms of different mass. By manipulating the entangled pairs using laser induced Bragg transitions and measuring the resulting correlations, we will study how gravity affects mass-entangled particles.

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.

Experimental quantum simulation with ultracold metastable Helium atoms in an optical lattice

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.

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.

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.

Interactions between antimatter and ultracold atoms

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.

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.

Efficient optical interconnect for quantum computers

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.
