Computing with pressure

Squish carbon and compute with it
  [vote for,

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. https://en.wikipedia.org/wiki/Cooper_pair

       Gasses generally have to be squished to be liquid, in fact liquid helium used to super-cool things is made by squishing. You might have just rediscovered some high school science.

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

       It amounts to using temperature because the basis for superconductivity and cooper pairs is not having any wiggle in the lattice. If you stick your finger over the end of a bicycle pump and press the cylinder, the pressure and temperature of the tube will go up, but you'll only get closer to a thermodynamically inactive state once the bike pump has cooled down i.e. allowed to settle in a more ordered state more conducive of cooper pairs. See! Its linked innit ?
