Computer chip shatters speed records: Solve the “absolute zero” problem, and this baby’s yours.
The chip only ran at the high speed when it was cooled to 451 degrees below zero — just 8 degrees above absolute zero, the coldest temperature possible in nature […]
And get this:
It took researchers nine months to invent a new process to clock the chip by injecting liquid helium into a probing station. Scientists can view the process through a powerful electronic microscope zoomed to see the tiny chip, only a few thousandths of a millimeter wide.
