Just in Case You Want to Simulate an Ising Spin Glass Model

This is just a short update to include a link to the solver code developed by Matthias Troyer et al. that I discussed in my last blog post. The advantage of conventional open source code is that everybody can play with … Continue reading

A Bet Lost, Despite Entanglement

And Why There Still May be Some Free Cheese in my Future. Occasionally I like to bet. And in Matthias Troyer I found somebody who took me up on it.  I wrote about this bet a while ago, but back … Continue reading

D-Wave Withdrawal Relief

For anybody needing an immediate dose of D-Wave news, Wired has this long, well researched article (Robert R. Tucci summarized it in visual form on his blog). It strikes a pretty objective tone, yet I find the uncritical acceptance of … Continue reading

Scott Aaronson (again) resigns as chief D-Wave critic and endorses their experiments

An exercise in positive spin. Update below. The English language is astoundingly malleable. It feels almost as if it was tailor made for marketing spin. I noticed this long ago (feels like a lifetime) when working in a position that … Continue reading

Out of the AI Winter and into the Cold

Any quantum computer using superconducting Josephson junctions will have to be operated at extremely low temperatures. The D-Wave machine, for instance, runs at about 20 mK, which is much colder than anything in nature (including deep space). A logarithmic scale … Continue reading
