Does High Temperature Superconductivity Reside in Plane or Charge Reservoir (CR) Oxygen, in YBa2Cu3O7 (YBC)? One of the outstanding problems in contemporary solid state physics concerns the mechanism of high temperature superconductivity (HTS). In particular, what binds charges that normally repel one another, into (Cooper) pairs? Closely related to this question is where the superconductivity resides in the material. We aim to answer the latter question in the much studied prototypical HTS YBa2 ....Does High Temperature Superconductivity Reside in Plane or Charge Reservoir (CR) Oxygen, in YBa2Cu3O7 (YBC)? One of the outstanding problems in contemporary solid state physics concerns the mechanism of high temperature superconductivity (HTS). In particular, what binds charges that normally repel one another, into (Cooper) pairs? Closely related to this question is where the superconductivity resides in the material. We aim to answer the latter question in the much studied prototypical HTS YBa2Cu3O7. In doing so we expect to demonstrate that phonons, widely believed not to play a role in HTS are in fact an important component in the HTS pairing mechanism.Read moreRead less
Decoherence in quantum computing and quantum electromechanical systems. Australia is one of the world leaders in fundamental studies and implementation of quantum computing and quantum electromechanical systems. By developing a framework to quantify and control noise due to decoherence in such systems, this research will facilitate progress in the development and understanding of quantum computing and quantum electromechanical devices. The project will also significantly strengthen the general r ....Decoherence in quantum computing and quantum electromechanical systems. Australia is one of the world leaders in fundamental studies and implementation of quantum computing and quantum electromechanical systems. By developing a framework to quantify and control noise due to decoherence in such systems, this research will facilitate progress in the development and understanding of quantum computing and quantum electromechanical devices. The project will also significantly strengthen the general representation of research on decoherence, a field of crucial importance to many areas of theoretical and experimental physics, in Australia. Funding of this project will enable Australia to further expand its leading position in cutting-edge science and next-generation technology.

Centre for Quantum Computer Technology. Development of a quantum computer (QC) for massively parallel computing is one of the major challenges in science and engineering this century. Since 2000 the Centre has achieved two major breakthroughs in this field: constructing the key functional element of a silicon solid-state QC; and co-inventing a scheme for efficient linear optics QC. The proposed CoE aims to align these two nationally co-ordinated research programs with the world's existing comput ....Centre for Quantum Computer Technology. Development of a quantum computer (QC) for massively parallel computing is one of the major challenges in science and engineering this century. Since 2000 the Centre has achieved two major breakthroughs in this field: constructing the key functional element of a silicon solid-state QC; and co-inventing a scheme for efficient linear optics QC. The proposed CoE aims to align these two nationally co-ordinated research programs with the world's existing computer and IT industries to realise a fault-tolerant multiple qubit quantum processor with integrated control and qubit chips, and develop a scaleable optical quantum processor providing significant economic benefit to Australia.Read moreRead less
