Quantum light manipulation enables record-breaking optical switching and beam-steering.

Researchers at the University of Arizona have published an article in Science Advances discussing the use of light-based optical computing to develop ultrafast electronics. The team used all-optical switching of a light signal on and off to reach data transfer speeds exceeding a petahertz, measured at the attosecond time scale. This new advancement would allow the encoding of data on ultrafast laser pulses, increasing the data transfer speed and opening a new realm of information technology.
