Computer scientists established a new boundary on computationally verifiable knowledge. In doing so, they solved major open problems in quantum mechanics and pure mathematics.
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.
The universe of problems that a computer can check has grown. The researchers’ secret ingredient? Quantum entanglement.
A two-player game can reveal whether the universe has an infinite amount of complexity.
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
