So say it is 1/10th of a picosecond, that would be 10 TRILLION operations per second.
While this is really impressive, don't hold your breath to see see it on the market… As I understand the paper the setup is very special to find out the switching time for the single device.
So challenges are:
* reproduce the result
* find out how to make an actual working device from it.
* characterize that one.
* find out how to make a complex device without losing the advantage
* characterize that one
* find a way to mass produce devices.
* show that to investors
* go for mass production.
In my opinion we suffer in science from having to beat our drum, and to project far into a future to find the "breakthrough".
The research is great in finding an ultrafast switch and being able to characterize it. An application in computing is very far away.
