A Quantum Trick Implied Eternal Stability. Now the Idea May Be Falling Apart.
A series of advances seemed to promise the impossible: the existence of quantum states that would never, ever fall into disarray. But physicists are now discovering that the pull of disorder may not be so easily overcome.
Never-Repeating Tiles Can Safeguard Quantum Information
Two researchers have proved that Penrose tilings, famous patterns that never repeat, are mathematically equivalent to a kind of quantum error correction.
Inside Scientists’ Life-Saving Prediction of the Iceland Eruption
The Reykjanes Peninsula has entered a new volcanic era. Innovative efforts to map and monitor the subterranean magma are saving lives.
The astrophysicist Erin Kara measures time lags in black holes’ X-ray glows, which reveal the complexity of the objects’ closest surroundings.
Radio Maps May Reveal the Universe’s Biggest Magnetic Fields
A controversial technique has produced detailed maps of the magnetic fields in colossal galaxy clusters. If confirmed, the approach could be used to reveal where cosmic magnetic fields come from.
In a ‘Dark Dimension,’ Physicists Search for the Universe’s Missing Matter
An idea derived from string theory suggests that dark matter is hiding in a (relatively) large extra dimension. The theory makes testable predictions that physicists are investigating now.
