An in-depth look at the engineering inside a quantum computer, and also demonstrating the operational results live and how they are measured.
With Professor Andrea Morello who is the Scientia Professor of quantum engineering in the School of Electrical Engineering and Telecommunications at the University of New South Wales, and a Program Manager at the ARC Centre of Excellence for Quantum Computation and Communication Technology.
