It seems like every time we turn around, there's another new smartphone or robotic butler pouring coffee in our laps. On Uncertain Principles, the engineering breakthroughs du jour are "technical advances in ion trap quantum computing." Chad Orzel explains, "previous experiments have used optical frequencies to manipulate the states of the ions, using light from very complicated laser systems." Such lasers (though effective) are unwieldy, and researchers are now using simple microwaves to perform the same functions. This promises quantum computers on a chip—eventually. Meanwhile, on the…
