They are -fast- approaching a width of 1 atom. 30nm isn't going to happen in the next few years. And 30nm still isn't close to the width of a single atom. IBM has demonstrated 6nm transistors. >If you have read much about Quantum computing, it is useless for many >applications. Quantum computing is useful only for highly parallel problems. For many problems, parallel algorithms can be devised to replace the serial ones that run well on today's computers. >Quantum computers run at ridiculously low speeds right now -- a few Hz. Key words being "right now". The forerunners of today's computers didn't run any faster, and technology is accelerating. >Aggressive estimates are viable quantum computers in about 20 years.

I wouldn't be surprised to see asynchronous chips being seriously considered soon. The clock-based approach is beginning to cause lots of problems as speed is agressively increased.
