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.
How quantum entanglement connects with the “many worlds” of quantum theory.
Bizarre quantum bonds connect distinct moments in time, suggesting that quantum links — not space-time — constitute the fundamental structure of the universe.
