In this talk I will ask: Can a classical system mimic a quantum system? Or, in terms of a specific example, can we design a classical circuit that emulates a quantum computer? The advance of this work is to demonstrate a way to construct complex classical networks that mimic the states and many of the correlations that are signatures of quantum systems. The talk will discuss whether classical systems that mimic quantum states exist. If so, how do we find them? What do they look like? Can they show entanglement? That work segues into the question of measurement of genuine quantum states and I will describe a proposal for how to understand measurements on the separated subsystems of an entangled state, which gives a solution to one of the issues raised by Einstein in the EPR paper published 90 years ago.
Greg Scholes is the William S. Tod Professor of Chemistry at Princeton University. Originally from Melbourne, Australia, he later undertook postdoctoral training at Imperial College London and University of California Berkeley. He started his independent career at the University of Toronto (2000-2014) where he was the D.J. LeRoy Distinguished Professor. He was appointed Editor-in-Chief of the Journal of Physical Chemistry Letters in 2019. Dr. Scholes was elected a Fellow of the Royal Society (London) in 2019 and a Fellow of the Royal Society of Canada in 2009. He served as Chair of Department at Princeton 2020-2023 and Director of an Energy Frontier Research Center (BioLEC) since 2018.
