According to the journal Phys.org, in the future, this will help create ultrafast computing devices. Specifically, for computers whose pulse frequency is equivalent to light wave oscillation. Bringing electrons to the speed of light helps speed up computers and other electronic devices in the future. The physicists developed the experiment with an ultra-fast laser, capable of generating one hundred million pulses of light per second. The design also includes gold nanostructures suitable for electronic manipulation and high-precision measurements.
