This project aims to develop the technology to connect superconducting quantum computers to the future quantum internet: an optical interconnect. Superconducting qubits are a leading quantum computing system, but their practical use is limited by their microwave operation frequency, as global quantum networks will operate at optical frequencies. This project aims to solve this problem by converting the microwave photons that carry superconducting quantum information to optical photons. To achieve high efficiency the project will investigate magnetically ordered rare-earth crystals, which uniquely possess the strong optical and microwave coupling required, to build a converter that could greatly enhance the capabilities of quantum computers.Read moreRead less

The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity. The project plans to investigate these phases in dipolar gases, which provide a clean, controlled environment for novel many-body phenomena. Within this setting, it plans to test established theories of pairing and develop accurate descriptions of density modulations, thus providing fundamental insights into strongly correlated systems. The new states of matter discovered in the project could form the basis for new quantum devices; in particular, a deeper understanding of stripe phases may allow us to use them for data storage.Read moreRead less
