SUMMARY:Condensed matter in two and three dimensions: Quantum simulations o
 n a D-Wave processor – Andrew King (1D-Wave Systems Inc.)
DESCRIPTION:ATTENTION: Unsual room: G-415 Roger-Gaudry\, UdeM
\nCondensed m
 atter in two and three dimensions: Quantum simulations on a D-Wave process
 or
\nAndrew King\, 1D-Wave Systems Inc.\, Burnaby\, British Columbia\, Ca
 nada. 2Vector Institute\, MaRS Centre\, Toronto\, Ontario\, Canada.
\nAbst
 ract:Quantum annealing processors developed and sold by D-Wave systems imp
 lement the transverse-field Ising model in superconducting flux qubits.  
 Although the initial intention was to solve classical optimization problem
 s using the adiabatic algorithm\, new control knobs allow us to probe quan
 tum systems with a significant transverse field.  Here I will discuss two
  such experiments: first\, an investigation of spin-glass / ferromagnetic 
 / paramagnetic phase transitions in a 3D cubic lattice (Science 165\, pp16
 2-165\, 2018)\; second\, an investigation of a Kosterlitz-Thouless phase t
 ransition in a fully-frustrated 2D lattice (Nature 560\, pp456-460\, 2018)
 .  These demonstrations of programmable quantum simulation at mesoscopic 
 scale represent a (non-universal) step towards Richard Feynman's vision of
  universal quantum simulators.   Bio:   Andrew King is a performance re
 searcher at D-Wave Systems.  Since joining in 2013\, his research has dri
 fted from optimization algorithms towards performance enhancement in quant
 um annealing and simulation of condensed matter systems.  He received his
  doctorate in computer science at McGill in 2009\, and worked as a postdoc
 toral researcher at the Institute for Theoretical Informatics in Prague\, 
 Columbia University in New York\, and Simon Fraser University in Burnaby.
   He is currently located in Montreal.
