Quantum Computing

What It Actually Is, Why It Matters, and What It Can (and Can't) Do

Quantum computers won't replace your laptop, won't think faster than your brain, and won't solve most problems any better than existing machines. But for a specific set of challenges—ones that matter enormously—they'll do something no classical computer ever could, no matter how powerful. Understanding what that something is, and isn't, is worth about an hour of your time.
