Fastest-ever logic gates could make computers a million times faster

2022-05-14 03:00:05

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser pulses, the new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”

Logic gates take two inputs, compare them, and then output a signal based on the result. They can, for example, output a 1 if both incoming signals are a 1 or a 0, or if either or neither of them is a 1, among other “rules.” Billions of individual logic gates are crammed into chips to create processors, memory and other electronic components.

Graphene can do everything, except for leaving the lab. Call me again when anybody can produce any appreciably useful quantity of the stuff and we can actually do the 50 million things that it's allegedly been found useful for in a lab scenario.

Prove it and then sell the patent for big money.

Don't even care about "big money".

That's also how small medical labs work too.
