Credit: ARC Centre for Quantum Computation and Communication, at UNSW The shift from fragile, bulky vacuum tubes to solid-state transistors paved the way for the information age. And the steady downsizing of transistors has made the devices of the information age ubiquitous, thanks to processors that become smaller, cheaper and faster with each passing year.
