The learning algorithm that enables the runaway success of deep neural networks doesn’t work in biological brains, but researchers are finding alternatives that could.
The result highlights a fundamental tension: Either the rules of quantum mechanics don’t always apply, or at least one basic assumption about reality must be wrong.
Deep neural networks, often criticized as “black boxes,” are helping neuroscientists understand the organization of living brains.
Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.
The Frauchiger-Renner thought experiment has shaken up the world of quantum foundations.
A quickly closed loophole has proved that the “great smoky dragon” of quantum mechanics may forever elude capture.
