Simulating quantum states of matter: connecting theory to applications in science and technology. Quantum phenomena are ubiquitous and critical to the functioning of many modern technological devices, for example sensors and computer chips used in mobile phones. Although great strides have been made in recent decades in describing quantum phenomena theoretically, computational modelling is an essential ingredient to describe real experiments and devices.

Quantum phenomena are ubiquitous and critical to the functioning of many modern technological devices, for example sensors and computer chips used in mobile phones. Although great strides have been made in recent decades in describing quantum phenomena theoretically, computational modelling is an essential ingredient to describe real experiments and devices. This project aims to develop the next generation of computational tools aimed at two major themes: characterising topological states of matter, and modelling non-equilibrium phenomena. These tools will be invaluable for the design and modelling of quantum devices and novel materials and will enable the development of the next generation of technological devices.Read moreRead less
Topological superconductivity and spin electronics in silicon and germanium. This project will exploit recent breakthroughs in materials growth, theoretical physics and micromagnet technology to design and build a new platform for future quantum devices and topological quantum computers. Instead of using exotic materials, we will fabricate hybrid superconductor-semiconductor devices with conventional silicon and germanium semiconductors, using the same nanofabrication techniques that industry us ....Topological superconductivity and spin electronics in silicon and germanium. This project will exploit recent breakthroughs in materials growth, theoretical physics and micromagnet technology to design and build a new platform for future quantum devices and topological quantum computers. Instead of using exotic materials, we will fabricate hybrid superconductor-semiconductor devices with conventional silicon and germanium semiconductors, using the same nanofabrication techniques that industry uses to create integrated circuits. The outcome will be an entirely new approach to hosting topological modes, in an architecture that can be scaled to make topological based qubits, using industrially compatible semiconductors.

Understanding and eliminating dissipation in superconducting devices: the origin of two-level defects. Superconducting quantum circuits constitute the next generation of nano-electronics. They find application in medicine, biology and geophysics; from mapping mineral deposits to imaging heart function, and are a promising candidate for quantum information processing and high speed electronics. A major loss mechanism within a Josephson junction (which forms the basis of a quantum circuit) is caus ....Understanding and eliminating dissipation in superconducting devices: the origin of two-level defects. Superconducting quantum circuits constitute the next generation of nano-electronics. They find application in medicine, biology and geophysics; from mapping mineral deposits to imaging heart function, and are a promising candidate for quantum information processing and high speed electronics. A major loss mechanism within a Josephson junction (which forms the basis of a quantum circuit) is caused by intrinsic two-level defects. What is not known is the true microscopic nature of these defects, although there are many theories. This project aims to unravel this mystery using detailed theoretical and computation analysis based on precision experimental characterisation.Read moreRead less
Hole quantum dots - a new spin on quantum information technology. Most electronic devices are powered by conventional transistors that use a 50 year old technology which is nearing the end of its lifetime. Spin-based electronics uses the electron's spin instead of its charge to store, process and transfer information. Although half of all transistors on a chip use holes, almost all research has focussed on electrons. Holes have completely different spin properties than electrons and are predicte ....Hole quantum dots - a new spin on quantum information technology. Most electronic devices are powered by conventional transistors that use a 50 year old technology which is nearing the end of its lifetime. Spin-based electronics uses the electron's spin instead of its charge to store, process and transfer information. Although half of all transistors on a chip use holes, almost all research has focussed on electrons. Holes have completely different spin properties than electrons and are predicted to have significant advantages for spin based quantum information processing. This project aims to develop single hole quantum dots, test theoretical predictions of the superiority of holes over electrons and develop new techniques for all-electrical spin manipulation.Read moreRead less

Future advances in computer technology will exploit quantum physics to deliver increased computational power, either through new materials or quantum information approaches. However although half of the 100 billion transistors in your iphone use holes to operate, most semiconductor quantum research has focussed on electrons. Holes have completely different quantum spin properties than electrons; recent advances show holes have highly desirable properties for spin based quantum information. This project will work with leading European laboratories to develop quantum computer components based on hole spin in quantum dots in industrially relevant semiconductors, and demonstrate a pathway towards a scalable quantum computer architecture.
