What’s the best way to solve hard problems? That’s the question at the heart of a subfield of computer science called computational complexity theory. It’s a hard question to answer, but flip it ...

Researchers have developed an algorithm that enhances the ability of a quantum computer to more efficiently find the best solution for complicated problems. Tohoku University researchers have ...

In 1994, a mathematician figured out how to make a quantum computer do something that no ordinary classical computer could. The work revealed that, in principle, a machine based on the rules of ...
