It won't hit PC levels until either cryogenics are commodity sized and priced for the home market, or room-temperature superconductors arrive and prove themselves still able to exhibit the Weird Quantum Effects that cold ones have. Look up "Josephson junctions", they're basically the transistors of QC.





My ideas are very fuzzy, but when people say that you can't run quantum computations at high temperature because of noise, it reminds me of something I read not too long ago about how scientists are starting to have insight into how biological systems operate in the presence of large amounts of noise from heat. So I wonder if there's a trick to it that nature already has found.

I'm no scientist but I would be very surprised if the brain is not harnessing similar effects or processes somehow. Consider microtubules, for example.
