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.

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.

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.

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.

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.

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.
