D-Wave processor architecture & device articles

Here are some links to articles describing key devices and systems within D-Wave adiabatic quantum optimization (AQO) processors. The processors contain three major subsystems:

  1. A programmable computing fabric consisting of two types of device, qubits and couplers;
  2. On-chip programmable magnetic memory for loading the problem to be solved onto the chip; and
  3. A readout system for reading out the result of a computation.

On a related note, I have been writing a book summarizing what we know about the processor. This is a draft of the current Preface:

This text is an introduction to a new type of superconducting processor, which is designed to harness quantum mechanics to solve hard optimization problems in a novel way. Because there are so many different scientific communities interested in quantum computation and quantum information, each with their own backgrounds and interests, we’ve split this material into three separate volumes.

In this, the first volume, we start at the lowest level of abstraction. Here we describe the devices and major subsystems of the processors under development. This material is at a level appropriate for experimental and theoretical physicists with backgrounds in condensed matter physics.

In volume two, we provide a compilation of experiments and experimental results, focusing on the use of the entire processor. This volume will have as its primary audience physicists and computer scientists whose interests lie in the performance of the system as a whole, in particular on specially crafted hard synthetic problems.

In the third and final volume, we abstract yet further and describe, using a series of examples, how to go from a high level problem specification down to the quantum computing processor. This material is targeted primarily to applications developers and computer scientists who are interested in the practical usage of this system for problem solving.

What do you guys think? Is this something you’d be interested in reading?

  1. I have no formal education regarding theoretical physics, sadly, despite how much I’m interested in it. Chances are I wouldn’t be able to understand the book even if I got my hands on a copy.

    …it is hard for me to learn quantum mechanics when I’m still eternally struggling with 10th grade geometry -.-
