Two new advances toward building the first practical quantum computer

• Quanticles 12y ago
  "square quantum bit circuit design that is the only physical architecture that could successfully scale to larger dimensions" There's really only one way to to possibly do things?
  • Strilanc 12y ago
    No, there's not only one way. Also, IBM did not invent/discover the layout in question (I think?). The article does tone it down later on, at least: > IBM's design shows the best potential to scale by adding more qubits to arrive at a working quantum system The surface code [0] is a good bet in the which-layout-will-work-first race. Mostly because the existing manufacturing capabilities are limited to working on a surface (as opposed to in 3d), and because the surface code has a good threshold error rate (~1%). John Martinis talked about the surface code in a google tech talk [1]. 0: http://arxiv.org/pdf/1208.0928.pdf http://arxiv.org/pdf/1208.0928.pdf 1: https://youtu.be/HQmFEt6l6Tw?t=21m24s https://youtu.be/HQmFEt6l6Tw?t=21m24s
