‘Sudden death’ of quantum fluctuations defies current theories of superconductivity

Researchers demonstrate that quantum entanglement and topology are inextricably linked

Newswise — For the first time, researchers from the Structured Light Laboratory (School of Physics) at the University of the Witwatersrand in South Africa, led by Professor Andrew Forbes, in collaboration with…

First direct imaging of tiny noble gas clusters at room temperature

Generating stable qubits at room temperature

Incorporating a chromophore in a metal-organic framework suppressed the molecular motion sufficiently to maintain the quantum coherence of the quintet state for more than 100 nanoseconds. Credit: Nobuhiro Yanai A…

Research offers insights into the metal-to-insulator transition without breaking symmetry

Credit: Yale University Metal-to-insulator transition—a process that turns materials from a conductor to an insulator—has been a crucial process behind microelectronic switches, nonvolatile memory, and neuromorphic computing materials. In many…

In novel quantum computer design, qubits use magnets to selectively communicate

Researchers have demonstrated that qubits (represented by the spheres and arrows) can “talk” to each other through a magnet (represented by the rectangular solid) rather than through air. This technology…

New study uses machine learning to bridge the reality gap in quantum devices

Quantum particles retain intrinsic features

Newswise — The quantum Cheshire cat effect draws its name from the fictional Cheshire Cat in the Alice in Wonderland story. That cat was able to disappear, leaving only its grin behind.…

NASA’s Webb Finds Signs of Possible Aurorae on Isolated Brown Dwarf

Newswise — Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane,…
