15 November 2013 – For a few years now we have been promised quantum computers. The media has been full of reports. It makes use of all that “spooky” quantum stuff and vastly increases computing power, right? And they’ll be under every desk when scientists finally tame the spooky stuff, right? And computing will undergo a revolution no less profound than the one that brought us the microchip, right? Wow. Another “tectonic-major-disruptive-paradigm-shift-game-changing” thingie. Cool. Will it be on the App Store?

We’ve actually been following quantum computing for awhile, through Greg’s contacts at CERN and IBM Research and mine at the Institute for Theoretical Physics at the University of Ulm, Germany.

It is fascinating stuff … and yes, having degrees in physics and computer science helps … but of late it has been a hot topic made more prominent with the big news this past Spring of the quantum computer collaboration among Google, NASA and D-Wave not least of which is the fact that futurist and artificial intelligence expert Ray Kurzweil (now Director of Engineering at … Read more
