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.

Multi-parameter state estimation at the fundamental precision limit

Dr Syed Assad, Professor Ping Koy Lam, Mr Lorcan Conlon, Dr Jie Zhao

Develop an active vibraiton isolation platform to provide a quiet, small displacement environment for high precision inteferometry.

In this project, we study the gravitational-wave astronomy and astrophysics science cases and observational prospects with future ground-based gravitational-wave observatories.

Construct a small dual tosion pendulum which have their centre of mass co-incide and their rotational axis colinear. Inital diagnostics will be done using shadow sensors.

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.

Precise Earth gratitational field measurements with laser-ranging interferometry.

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.

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.

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.

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.

Metasurface can the generation and manipulation of polarization-entangled photon pairs at the nanoscale.

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.

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.

Using non-classical light states on laser interferometric gravitational-wave detectors, to further enhance the best length measurement devices in the world.

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 aims to realise various useful artificial gauge fields for cavity photons and exciton polaritons. These fields are expected to be non-Hermitian and can be used to combine effects of non-Hermiticity and topology, e.g. topological edge states and non-Hermitian skin effect. Realising these non-Hermitian fields is an important step towards practical applications of exciton-polariton condensates and superfluids.

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.

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.

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.

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.
