What's up in
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.
