The Sandia quantum transistor is not the first to use a quantum mechanical effect called ``tunneling'' to compute. Experimental quantum tunneling devices were first made nearly a decade ago.
But Sandia's is the first to be made using common manufacturing techniques that would allow many of the devices to be strung together to compute en masse, said physicist Jerry Simmons, leader of the Sandia development team.
And you know what the coolest part of this story is? Jerry Simmons is my brother! Go man, go! I can only hope that he'll remember the little people in his life when he sells this technology to chipmakers world-wide! *wink*
