Silicon Valley is awash in hype about quantum computers. But these new machines—which perform calculations not only with bits (ones and zeros) but also with mysterious things called qubits—are still in their infancy. They are very large, very expensive, and must be kept very cold. Their applications are limited, and it will be likely a decade before they can be put to practical use. Tom Simonite, WIRED’s reporter who covers the esoteric end of computing, joins the show to explain what quantum computing is, how it works, and why it’s going to change our future. And we’re pretty sure we understand it now. Kinda. Some notes: Read Tom’s WIRED Guide on quantum computing. Recommendations this week: Philips Wake-Up Light for a different way to start the day.
