The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light that could be used to create strange materials called time crystals. … It could also help with more everyday applications, says Maxim Shcherbakov, [assistant professor, electrical engineering and computer science], at the University of California, Irvine. “The temporal interference is an exciting find that can see applications in many modern technologies but especially in telecommunications, where the way we treat signals in time is very important,” he says.
