Probably just a miscommunication. The actual improvement is more like 10K times, but this moves from the 'gigahertz range' to the 'petahertz range' which differ by 1e6.
> "Since light oscillates so fast (roughly a few hundred million times per second), using light could speed up electronics by a factor of roughly 10 000 as compared to computer chips,” says Tobias Boolakee, a laser physicist in Peter Hommelhoff’s group at the FAU and the first author of a study in Nature on the new gate."

- oh_my_goodness 4y agoLight oscillates much, much faster than a few hundred million times per second. Take 1 micron wavelength. At a speed of 3e8 m/s, 1 micron light oscillates 3e8/1e-6 = 3e14 times per second. Three times ten to the fourteenth power. For anybody who doesn't juggle large numbers every day, a hundred million is 1e8. Ten to the eighth.
- photochemsyn 4y agoMaybe they meant trillions? The 10,000 times faster number seems correct though, as fiber optic carries light at ~200-300 THz and 10 GHz is the electronic standard at present.
