Bio

Professor David J. Reilly joined Microsoft in 2017 where he is Partner and Director of Microsoft Quantum – Sydney and a Professor in the School of Physics, The University of Sydney. The focus of much of Reilly’s work is at the quantum-classical interface and the scale-up of quantum technology. As a leader in Microsoft’s quantum effort he bridges the gap between fundamental quantum physics and the engineering approaches need to scale quantum devices into quantum machines. Prior to joining the University of Sydney, Reilly was a postdoctoral Fellow at Harvard University (USA) and has held a Fellowship from Hewlett- Packard. Born in Sydney Australia, he hold degrees from UNSW (Ph.D) and UTS (B.App.Science Hons-1).

Abstract

With modern fabrication techniques it’s not crazy to imagine soon creating chips that contain thousands of qubits. Maybe they’re great qubits. Maybe they’re broken. How to tell? Today, it’s not possible to control and readout more than 100 qubits, no matter if they are good, bad, or ugly. We are at the limit of control using traditional room temperature electronics and hamstrung by the  ‘IO bottleneck’ that is inherent in quantum computing. This talk will discuss this scaling barrier and approaches to overcome it that make use of new physics and new engineering solutions.
