In today's issue of the journal Nature there is a article about a Silicon based Quantum Computer that operates at temperatures as high as 1.25 degrees Kelvin with an error rate of only 0.7%. That may seem pretty cold but previous Silicon based Quantum Computers, the type corporate investors like best, needed 0.01 degrees Kelvin. Compared with that 1.25 is blistering hot.

It’s a coupla orders of magnitude cheaper to maintain something at 1.25K compared to .01K as well.  I don’t have the exact numbers on that, but commercially it is a game changer if it is proven.
