Superconductivity Mystery: Scientists Challenge a 50-Year Theory of Electron Behavior

A recent study found that the Hubbard model failed to accurately predict the behavior of a simplified one-dimensional cuprate system. According to scientists at SLAC, this suggests the model is unlikely to fully account for high-temperature superconductivity in two-dimensional cuprates.

Superconductivity, the phenomenon where certain materials can conduct electricity without any energy loss, holds great potential for revolutionary technologies, from ultra-efficient power grids to cutting-edge quantum devices.

A recent study published in Physical Review Letters.

The Quantum Zoo Just Got Wilder: Magnet-Free States Discovered in Twisted Crystals

A mysterious menagerie of quantum states — once purely theoretical — has been brought to life by researchers at Columbia using twisted molybdenum ditelluride.

These newly observed states, some never seen before, hint at the possibility of topological quantum computers that don’t require magnetic fields, overcoming a major obstacle in the field. By employing a highly sensitive optical technique, scientists have not only identified a range of exotic quantum states but also demonstrated a new experimental approach that may transform the way we study quantum matter.

Quantum Leap: Scientists Slash Atom Superposition Time by 10,000x

Working with the Quantum Statistical Physics (PQS) group, Dengis developed a protocol for rapidly generating NOON states. “These states, which look like miniature versions of Schrödinger’s famous cat, are quantum superpositions,” he explains. “They are of major interest for technologies such as ultra-precise quantum sensors or quantum computers.”

The obstacle of time

The main challenge? Manufacturing these states normally takes far too long. We’re talking tens of minutes or more, which often exceeds the lifetime of the experiment. The cause? An energy bottleneck, a “sharp bend” in the system’s evolution that forces it to slow down.

Ripple’s xrpl.js npm Package Backdoored to Steal Private Keys in Major Supply Chain Attack

The Ripple cryptocurrency npm JavaScript library named xrpl.js has been compromised by unknown threat actors as part of a software supply chain attack designed to harvest and exfiltrate users’ private keys.

The malicious activity has been found to affect five different versions of the package: 4.2.1, 4.2.2, 4.2.3, 4.2.4, and 2.14.2. The issue has been addressed in versions 4.2.5 and 2.14.3.
