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 known as tunneling, they recorded electrons bypassing a physical barrier almost instantaneously, a feat that redefines the potential limits of computer processing power. A study ...
