Recent developments in quantum annealing

Summary: 

Troyer, Zintchenko and Brown (ETH Zurich) summary on recent developments in quantum annealing.

On December 7, researchers at Google have reported evidence for significant quantum effects on the latest D-Wave 2X device using problem instances that are designed to be hard for thermal annealing algorithms but easy for quantum annealers (http://arxiv.org/abs/1512.02206).

Matthias Troyer (member of the Virtual Institute for Quantum Theory) together with Ilia Zintchenko and Ethan Brown (ETH Zurich) has written a brief report meant to give a technical summary of the results to scientists. The report is available here.
