- rwmj 1y agoIt seems the breakthrough is that you could use familiar semiconductor manufacturing processes. However the temperature is still going to be a major issue. I don't want a computer that requires liquid helium cooling.
- zahlman 1y ago> you could use familiar semiconductor manufacturing processes. Unclear to me why that's helpful. Materials that superconduct at a higher temperature than this one aren't hard to come by, or obscure: > In 1913, lead was found to superconduct at 7 K,
- lazide 1y agoProbably because they don’t behave well for normal lithography techniques? The high temp superconductors I know of are weird meta materials, and good luck getting them to exist in chip form at all.
- pwg 1y ago> I don't want a computer that requires liquid helium cooling. True, but I /can/ see someone, such as Sandia National Labs, very much willing to install a liquid helium cooled computer if it provides a significant performance increase above their existing supercomputer installations.
