DESCRIPTION:Co-authors: Sergio Boixo (Google Inc.)\, Sergei V.
  Isakov (Google Inc.)\, Zhihui Wang (ISI\, Univers
 ity of California)\, Joshua Job (ISI\, University 
 of California)\, Daniel Lidar (ISI\, University of
  California)\, John Martinis (Department of Physic
 s\, University of California)\, Matthias Troyer (E
 TH Zurich)\n\nWe are at a point where the first qu
 antum devices are becoming available both in labor
 atories and commercially. While universal quantum 
 computing still its infancy\, analogue devices\, s
 uch cold atoms experiments and quantum annealers\,
  constitute the first step towards using quantum h
 ardware for solving computational problems. In thi
 s talk\, we show that D-Wave devices closely follo
 ws the statistics of simulated quantum annealing\,
  whereas it is clearly different from semi-classic
 al spin dynamics and classical thermal annealing. 
 The theoretical study by Santoro [Science\, Santor
 o et al.\, 295 (5564)\, 2427]\, where it was shown
  that quantum annealing outperforms classical ther
 mal annealing\, suggests that the D-Wave machines 
 could have advantages over to classical hardware. 
 We discuss how one probe for such advantages corre
 ctly\, and we present preliminary results on the c
 omputational capabilities of the D-Wave devices.\n
