Existing quantum computers have a real problem: they tend to become incoherent when noise is added. That is, when the temperature of the wrong part rises for any reason. Wouldn't it be great if there were a different way to maintain pairing between particles besides very low temperatures?
At sufficiently
high pressure any material* will exhibit electron pairing. The other word for that is "superconductor". I read about an experiment wherein a 3000 nanometer piece of osmium was compressed at a more than high enough pressure to create pairing. It seems likely that a lithographed circuit made of carbon on an osmium backplane would have this characteristic, if put under sufficient pressure.
Now 3000 nanometers isn't a lot, but at contemporary feature sizes it can make about a 200 by 200 transistor processor. Such a processor could merge traditional processing at superconductive speeds with quantum magic, making a hybrid processor far more powerful than existing quantum computers.
*that has electrons
Cooper pairing works with electrons and, theoretically, with other fermions.

[bigsleep] see the link about electron pairing. It's not molecular bonding, and not directly related to the traditionally known states of matter. |
