Laser-Based Logic Gate Expedites Info Processing

A logic gate developed by researchers from the University of Rochester and the Friedrich-Alexander-Universität (FAU) Erlangen-Nürnberg operates at femtosecond timescales, potentially enabling information processing at the petahertz limit. Logic gates, which are the basic building blocks necessary for computation, control how incoming information taking the form of a 1 or 0 is processed. Logic gates require two input signals and yield a logic output.
