Researchers at IBM and the University of California are questioning whether a closely watched experimental computer used by Google actually relies on quantum mechanics as its manufacturer, D-Wave, claims.

At the heart of the battle is a question about the validity of quantum computing, which some predict may offer a road forward after Intel and other chip manufacturers exhaust "and reach the physical limits" of how powerful they can make their processors.

My Two Cents

I was lucky enough to listen to @hartmutneven at Google recently speak about Artificial Intelligence and Quantum Computing, including Google's work with D-Wave. So my big take-away regarding Dr. Neven's talk was -- if the D-Wave machine has 512 Qbits and they use 3 for OTHER, what and how are the remaining 509 Qbits doing and are they speaking to each other at all? Right now, according to Dr. Neven each CPU (Qbit) is only loosely coupled to an adjacent Qbit. Thus, not much interaction between the different Qbits. IMHO - not much Quantum -- but still hugely powerful and tremendously more powerful than other machines.
