Physicists produce symmetry-protected Majorana edge modes on a quantum computer

Artistic representation of Majorana edge modes on a string of superconducting qubits. Credit: Google Quantum AI Google Quantum AI physicists have used their quantum computer to study an efficient type of particle that is more resilient to environmental disturbances that can degrade quantum computations. These effective particles, known as Majorana edge modes, form as a …

New space observatory helps solve mystery involving huge black holes

New space observatory helps solve mystery involving huge black holes

Most galaxies are built around huge black holes. While many of them are relatively docile, like the one at the center of our Milky Way, some are ferocious – gobbling up surrounding material and releasing huge jets of extremely bright high-energy particles far into space. Using data from the recently deployed Imaging X-ray Polarimetry Explorer …

Explainable AI-based physical theory for designing advanced materials

An image illustrating the extended Landau free-energy model developed by a research team at Tokyo University of Science, which allows causal analysis of magnetization reversal in nanomagnets. Using this model, the team was able to effectively visualize the images of the magnetic domain and succeeded in the reverse design of low-power nanostructures. Credit: Tokyo University …

Cosmic chocolate pralines: surprising discovery of physicists on the structure of neutron stars

Studying the speed of sound has revealed that heavy neutron stars have a hard mantle and a soft core, while light neutron stars have a soft mantle and a hard core – much like different chocolate pralines. Credit: Peter Kiefer and Luciano Rezzolla Physicists are modeling more than a million equations of state to uncover …

Researchers develop programmable optical device for high-speed beam steering

Scientists have developed a wireless, programmable spatial light modulator that can manipulate light on the wavelength scale with orders of magnitude faster response than existing devices. 1 credit In a scene from “Star Wars: Episode IV – A New Hope”, R2D2 projects a three-dimensional hologram of Princess Leia making a desperate plea for help. This …
