Researchers Build 'The World's Fastest Petahertz Quantum Transistor'. They Predict Lightwave Electronics
"What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors?" asks the University of Arizona. "A team of scientists, including researchers from the University of Arizona, are working to make that possible." In a groundbreaking intern...
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 published in Nature Communications highlights how the technique could lead to processing speeds in the petahertz range — over 1,000 times faster than modern computer chips. Hassan has long pursued light-based computer technology and previously led efforts to develop the world's fastest electron microscope...
