This project aims to engineer novel quantum electronic devices based on strongly-coupled, one-dimensional superconducting microcircuits. These will be realised using chains of nanoscale superconducting islands fabricated on a chip. The project expects to achieve a special type of insulating state, where individual charges can be transported one by one. This would be significant as a primary standard that precisely links time (or frequency) to charge. The project also aims to create a current mirror device, in which a supercurrent sent down one chain induces a reflected supercurrent in the other, forming the basis of a new superconducting quantum bit. Other devices will be used to study a simplified model related to high temperature superconductors.Read moreRead less

The project aims to establish a state-of-the-art facility to conduct optics and photonics experiments at ultra-low temperatures, by integrating an optical-access cryogen-free dilution refrigerator into an optics laboratory. Near absolute zero temperature, complex materials and engineered nanoscale devices exhibit striking quantum mechanical behaviour. Experimental access to photonics at millikelvin temperatures would enable a coherent quantum-mechanical interface between spins, charges, phonons and photons. This unique facility may help in designing the next generation of information, communication and metrology devices, such as quantum computers, single-photon sources and detectors, and nanoscale quantum-enhanced sensors.Read moreRead less

This project aims to develop the science and tools behind device-independent quantum security for information networks. These gold-standard protocols rely on genuine quantum nonlocality but, to date, the strict performance requirements have been unachievable for general practical cases. Further, the theory of nonlocality in multiparty networks is almost completely undeveloped. The project’s anticipated outcomes are novel experiment and theory to bypass barriers and open up nonlocal network protocols. It is also expected to rigorously establish that a single-photon wavefunction after a beamsplitter is truly nonlocal. Likely future benefits include secure random numbers, secure distributed information technology and world-best photon sources.Read moreRead less

This project aims to develop more efficient algorithms to simulate quantum chemistry on quantum computers. Quantum computers have the potential to perform calculations that would be intractable for even the largest supercomputers, but need to be programmed in a radically different way to achieve this speed. One of the most important applications of quantum computers is to simulate quantum mechanics to predict the properties of molecules and materials, and thereby design them. Current quantum algorithms are very resource intensive, making them impractical for the foreseeable future. The expected outcome of this project is to provide much more efficient algorithms that can be run on quantum processors in the near future.Read moreRead less
