In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work.
Urmila Mahadev spent eight years in graduate school solving one of the most basic questions in quantum computation: How do you know whether a quantum computer has done anything quantum at all?
A visual prank exposes an Achilles’ heel of computer vision systems: Unlike humans, they can’t do a double take.
The nearest neighbor problem asks where a new point fits into an existing data set. A few researchers set out to prove that there was no universal way to solve it. Instead, they found such a way.
