Decoherence and Quantum Simulations of Spin-Environment systems. The effort to develop quantum technologies relies on our ability to understand and manipulate quantum mechanical objects with great precision. In order to do this, we need to study how such systems interact with their surroundings. Solid-state quantum systems connected to an environment show a rich range of phenomena, such as quantum phase transitions, which are interesting in their own right. This work will better enable experi ....Decoherence and Quantum Simulations of Spin-Environment systems.

Modelling Superconducting Quantum Devices. The capability to incorporate quantum mechanical systems into electronic circuits leads to devices with fundamentally new properties. These devices are very sensitive to their environment, so can be used as sensitive sensors. In the extreme, with many such devices connected together, it would lead to a full scale quantum computer, which has the capacity to perform tasks that are unfeasible on an ordinary computer. This proposal aims to characterise ....Modelling Superconducting Quantum Devices.

In the extreme, with many such devices connected together, it would lead to a full scale quantum computer, which has the capacity to perform tasks that are unfeasible on an ordinary computer. This proposal aims to characterise quantum electronics from a theoretical perspective, complimentary to experimental efforts that will soon begin at the University of Queensland.Read moreRead less

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.
