scaling is the key question. Not clear what the temp requirement is but near zero won't scale.

"One challenge facing scientists is that the spins of electrons, or any other quantum particles, are incredibly delicate. Any outside influences, whether a wisp of magnetism or glimpse of light, destabilizes the electrons' spins and introduces errors." Shielding from noise sources is going to be a toughie.

Resistion, I agree with your comment. A lab setting is one thing, but to scale up, it would imply that the system would have to spend large amonunt of resources to limit other sources of influence (NOISE). So from the start this new computing method is doomed. It is tough enough to control electrical domain, now add to the mix magnetic, radiation sources, gavity (?), etc...

this sounds like a headache.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
