Breakthrough: Fast superconducting transistor !
With no electric field, there is zero resistance between the source and drain as the device is superconducting
Caviglia said that computers using such transistors would be much faster than the gigahertz speeds currently available
How much faster? Well, expect computer clock order of 100 Ghz. That will simply performance smash current up to 3 Ghz clocked microprocessor snails.
Drawback? Well, working temperature is so prohibitively low that is far from ordinary home use.
Beside, Josephson junction superconducting switch was invented 40 years ago.
The same hard request for low temperature and low voltage made superconducting
computers elusive.
However, if someone could make them working at 77K or above, that would trigger some niche industrial interest. Because, in ordinary transistors, in the mean time, leaking power problems during its off state will only rise.
