Even if you could measure three black holes’ locations as precisely as physically possible, you still might not know where the black holes would go. Such a trio’s complex dance can be so chaotic that the motions are fundamentally unpredictable, new computer simulations show. The paths of three black holes orbiting each other can be […] More
Physicists have finally captured a superconductor’s wave. The first direct evidence of a phase of matter known as a pair-density wave helps reveal the physics that underlies mysterious high-temperature superconductors, which conduct electricity without resistance at surprisingly high temperatures. The wave was detected using a scanning tunneling microscope, researchers report April 1 in Nature. Physicists […] More
Physicists’ fantasies of a future quantum internet are a bit closer to reality. Scientists entangled two quantum “hard drives” that were linked by fibers tens of kilometers long. Entanglement, a type of ethereal quantum connection, allows two particles to behave as if intertwined even when distantly separated. The new study entangled two devices called quantum […] More
Containers that the U.S. government plans to use to store dangerous nuclear waste underground may be more vulnerable to water damage than previously thought. Millions of liters of highly radioactive waste from the U.S. nuclear weapons program are currently held in temporary storage units across the country. The government’s game plan for permanently disposing of […] More
A tiny nanoparticle has been chilled to the max. Physicists cooled a nanoparticle to the lowest temperature allowed by quantum mechanics. The particle’s motion reached what’s known as the ground state, or lowest possible energy level. In a typical material, the amount that its atoms jostle around indicates its temperature. But in the case […] More
Computer scientists’ daydreams have revealed the power of quantum mechanics. Imagine meeting omniscient beings who claim to have the solution to a complex problem that no computer could ever solve. You’d probably be at a loss to check the answer. But now, computer scientists report that quantum mechanics provides a way to quickly verify the […] More
Hotter objects typically glow brighter than cooler ones, making them stand out in infrared images. But a newly designed coating bucks the rule that hotter equals brighter. For certain wavelengths of infrared light, the material’s brightness doesn’t change as it warms, researchers report December 17 in Proceedings of the National Academy of Sciences. Made of […] More
Like Schrödinger’s cat, a 2019 claim of quantum supremacy seems to be simultaneously alive and dead. Thanks to the rules of quantum mechanics, the fabled feline occupies two contradictory states at once, and the same applies to this year’s most prominent quantum advance. In October, researchers from Google claimed to have achieved a milestone known […] More
