Big week in quantum computing hardware research!

D-Wave published a paper claiming 15-600x speedup over classical solvers. The articles below show some skepticism about what the speedup actually is, whether the comparisons are fair, and whether the quantum effects are responsible for the speedup.

Since D-Wave has been burned before by claiming large speedups, the arxiv paper is a much more serious evaluation of what the D-Wave machine can actually do. Independent evaluations have not been published yet.

Additionally, a group at the University of Bristol created a "quantum optics lab on a chip", which can be reprogrammed to implement any linear optical protocol, leading to quick experiments with massive applications in quantum computing.
