Quantum computing with spin systems (1/6)

by Dr Nicholas Chancellor (Durham)

Friday 17 Jul 2020, 14:00 → 15:00 Europe/London

In this talk I give a gentle introduction into applied quantum computing, and in particular the continuous time quantum computing my research has focused on. I briefly review my current and past work and where it fits into the broader context of quantum computing, including work which underpins an important tool for hybrid quantum/classical algorithms on the quantum computing devices produced by D-Wave Systems Inc. I discuss how this work relies on an interplay between physics and computing and how understanding of both is necessary, giving examples from some remote experiments I have performed. I then look to the future by discussing theoretical and numerical work on how more coherent devices should behave, and how the mechanism by which they solve problems can be understood as stemming from principles related to energy conservation. Finally, I discuss the bigger picture of how to make quantum computing a reality for solving real problems, and touch on the possibility of using so called 'quantum inspired' algorithms which do not rely on experimental advances in quantum devices.
