Outmaneuvering correlated noise in quantum computers. The project aims to characterise and control quantum machines available today. These machines overwhelmingly suffer from noise with complex structures. Thus, a key target of the project is to develop a theory to describe and manipulate complex quantum processes. The project then intends to apply this theory to commercial-grade quantum computers. This approach is anticipated to lead to a new understanding of time-correlated complex quantum pro ....Outmaneuvering correlated noise in quantum computers. The project aims to characterise and control quantum machines available today. These machines overwhelmingly suffer from noise with complex structures. Thus, a key target of the project is to develop a theory to describe and manipulate complex quantum processes. The project then intends to apply this theory to commercial-grade quantum computers. This approach is anticipated to lead to a new understanding of time-correlated complex quantum processes and develop methods to enhance the performance of today's quantum computers. Noise characterisation and mitigation should have commercial value and benefit research groups working to develop quantum technologies, both in Australia and internationally.Read moreRead less
Quantum measurement as a resource. Advanced quantum computers will use modular measurements significantly enhancing their capabilities. However, due to the noisy environment, the measurements may have nontrivial effects on the computation. Making best use of realistic (hence imperfect) measurements is a challenging problem that hinders the development of these technologies. This project, using modern tools of resource theory, aims to design optimal realistic measurement procedures for near-term ....Quantum measurement as a resource. Advanced quantum computers will use modular measurements significantly enhancing their capabilities. However, due to the noisy environment, the measurements may have nontrivial effects on the computation. Making best use of realistic (hence imperfect) measurements is a challenging problem that hinders the development of these technologies. This project, using modern tools of resource theory, aims to design optimal realistic measurement procedures for near-term noisy quantum devices. The expected outcomes of the project are refined methods to optimise quantum measurements in today's rudimentary quantum machines. This will provide a significant benefit to the Australian community, advancing the development of disruptive quantum technologies.Read moreRead less
Complex quantum dynamics for technological applications. This project aims to characterise dynamics of a quantum system immersed in a complex surrounding, such as a quantum computer interacting with an environment that remembers the computer’s past. Since there are no known methods for battling the effects of the environment on the computer when they are intertwined, this project will develop tools to combat these adverse effects. The project will discover physics of complex dynamics and investi ....Complex quantum dynamics for technological applications. This project aims to characterise dynamics of a quantum system immersed in a complex surrounding, such as a quantum computer interacting with an environment that remembers the computer’s past. Since there are no known methods for battling the effects of the environment on the computer when they are intertwined, this project will develop tools to combat these adverse effects. The project will discover physics of complex dynamics and investigate unexplored physical phenomena in the laboratory, like an antenna of photosynthetic systems that use complex surroundings for efficient and fast energy transport. The project is expected to help build new and improved quantum machines.Read moreRead less
