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
Gravity and quantum-limited measurements with a fundamental minimum length. This project aims to investigate the effects of a fundamental minimum length on the nature of gravity and on how accurately we can make measurements in our world. The key challenge is to combine our best theories of fundamental physics to model what happens at ultra-short distances. This project will generate new knowledge at this interface by using a novel approach inspired by information theory. The expected outcomes a ....Gravity and quantum-limited measurements with a fundamental minimum length. This project aims to investigate the effects of a fundamental minimum length on the nature of gravity and on how accurately we can make measurements in our world. The key challenge is to combine our best theories of fundamental physics to model what happens at ultra-short distances. This project will generate new knowledge at this interface by using a novel approach inspired by information theory. The expected outcomes are new connections between fundamental limitations on measurements, the nature of gravitation, and ultra-small-scale quantum physics. The benefit of this work is breaking the logjam in answering the most important open question in all of physics: how to unite quantum theory and gravitation.Read moreRead less
Noncommutative analysis and geometry in interaction with quantum physics. Quantum theory has produced many advances in our understanding of the physical world for the last hundred years while mathematical breakthroughs have been made through exploiting innovative ideas from quantum physics. This project continues in this highly successful framework and will lead to advances in geometry both classical and noncommutative.

Summary
Quantum computation and relativistic quantum information. Quantum information theory has profound implications both for practical computing and for our fundamental understanding of the universe. This project will determine the viability of one particular quantum computing platform and also develop theoretical and experimental tools to probe the interface between quantum theory and relativity.
