What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors? A team of scientists, including researchers from the University of Arizona, are ...

Researchers demonstrated a way to manipulate electrons in graphene using pulses of light that last less than one thousands trillionth (one quadrillionth) of a second. By leveraging a quantum effect ...

Editor's take: The University of Arizona could become the birthplace of the world's first petahertz-speed transistor. If successful, this research work could mark the dawn of a new era in computing, ...

New findings published by quantum scientists in Germany could pave the way towards computer chips that use light instead of electricity to control their internal logic. Where today's silicon-based ...

Semiconductor electronics is getting faster and faster - but at some point, physics no longer permits any increase. The speed can definitely not be increased beyond one petahertz (one million ...
