What's up in
A recent test has confirmed the predictions of quantum trajectory theory.
Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.
An experiment caught a quantum system in the middle of a jump — something the originators of quantum mechanics assumed was impossible.
The universe of problems that a computer can check has grown. The researchers’ secret ingredient? Quantum entanglement.
Quantum computers can’t selectively forget information. A new algorithm for multiplication shows a way around that problem.
A two-player game can reveal whether the universe has an infinite amount of complexity.
In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.
