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

Disruptive nanotechnology to control light. The project aims to develop approaches to control propagation of light in nonreciprocal ways, similar to ways we control directions of electric currents with semiconductor diodes and transistors.

The project aims to develop approaches to control propagation of light in nonreciprocal ways, similar to ways we control directions of electric currents with semiconductor diodes and transistors. Nonreciprocal behaviour of light is difficult to achieve, and it is currently limited to relatively large optical systems, which represents a road block for further miniaturisation and integration of optical devices. Expected outcomes of this project include first demonstrations of a radical miniaturisation of nonreciprocal optical components to the nanoscale. The outcomes should enrich our fundamental knowledge and assist the advancement of vital technologies such as integrated optical circuitry and communication infrastructure.Read moreRead less
