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.
These games combine quantum entanglement, infinity and impossible-to-calculate winning probabilities. But if researchers can crack them, they’ll reveal deep mathematical secrets.
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.
Recent experiments have put relatively large objects into quantum states, illuminating the processes by which the ordinary world emerges out of the quantum one.
A simple analogue could offer insights into one of the most astonishing results of quantum mechanics.
