Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Quantum computing just got hotter: One degree above absolute zero
For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or –273.15°C). That's because the quantum phenomena that grant quantum computers the.....»»
A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations
Entanglement is a widely studied quantum physics phenomenon, in which two particles become linked in such a way that the state of one affects the state of another, irrespective of the distance between them. When studying systems comprised of several.....»»
Quantum computing progress: Higher temps, better error correction
Amazon, IBM, and traditional silicon makers all working toward error correction. Enlarge (credit: vital) There's a strong consensus that tackling most useful problems with a quantum computer will require that the compute.....»»
Physicists demonstrate parity anomaly in a topological insulator
Experimental and theoretical physicists from the Würzburg Institute for Topological Insulators have observed a re-entrant quantum Hall effect in a mercury telluride device and have identified it as a signature of parity anomaly......»»
Scientists on the hunt for evidence of quantum gravity"s existence at the South Pole
Several thousand sensors distributed over a square kilometer near the South Pole are tasked with answering one of the large outstanding questions in physics: does quantum gravity exist? The sensors monitor neutrinos—particles with no electrical cha.....»»
Toward continuous reservoir monitoring from space
Most satellites are placed in orbit on 5-to-10-year missions to accomplish many tasks. One of the many functions of the satellites carrying a Moderate Resolution Imaging Spectroradiometer (MODIS) is to monitor water reservoirs around the world. A sig.....»»
