For more than a century, the laws of thermodynamics have helped us understand how energy moves, how engines work, and why time seems to flow in one direction. Now, researchers have made a similarly powerful discovery, but in the strange world of quantum physics. Scientists have shown for the first time that entanglement, the mysterious link between quantum particles, can …

Researchers at Harvard University have developed a new method for conducting complex quantum operations using a single, flat optical device. This device, known as a metasurface, can perform the functions of multiple conventional optical components, addressing a persistent technical hurdle in the field of photon-based quantum information processing. “In the race toward practical quantum computers and networks, photons — fundamental …

Century-Old Quantum Mystery Solved: Scientists Finally See Inside the Electron’s “Tunnel”  SciTechDaily Source link

Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them will doom most forms of cryptography. Several years ago, researchers found a radically new approach to encryption that lacks this potential weak spot. The approach exploits the peculiar features of …

Demonstration of first antimatter quantum bit paves the way for substantially improved tests of nature’s fundamental symmetries In a breakthrough for antimatter research, the BASE collaboration at CERN has kept an antiproton – the antimatter counterpart of a proton – oscillating smoothly between two different quantum states for almost a minute while trapped. The achievement, reported in a paper published today in the journal Nature, marks the …

For more than a century, physicists have relied on two separate rulebooks to describe nature. Quantum mechanics excels at explaining atoms, photons, and every jiggle inside laboratories. Einstein’s general relativity, meanwhile, accounts for the way planets and stars bend the very fabric of space-time. Each framework is staggeringly accurate inside its own arena, yet they cannot be combined in a …

The world of Bousso’s new theorem still departs from our universe in notable ways. For mathematical convenience, he assumed that there’s an unlimited variety of particles—an unrealistic assumption that makes some physicists wonder whether this third layer matches reality (with its 17 or so known particles) any better than the second layer does. “We don’t have an infinite number of …
