[ExI] Quantum Computers

[John Clark]

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.
