The calculations also help validate a method that will be used to make predictions for and analyze data from high-energy experiments at the future Electron-Ion Collider (EIC) at Brookhaven National Laboratory.

Explaining Science Through Dance

University of California San Diego — Tue, 05 Nov 2024 05:00:00 EST

Science can be difficult to explain to the public. Explaining a theoretical science concept to high school students requires a new way of thinking altogether, which is precisely what researchers at UC San Diego did when they orchestrated a dance with high school students at Orange Glen High School in Escondido as a way to explain topological insulators. The experiment was led by former graduate student Matthew Du and UC San Diego Associate Professor of Chemistry and Biochemistry Joel Yuen-Zhou.

Empa researchers and their partners have now achieved a breakthrough: Using a kind of "quantum Lego", they have been able to accurately realize a well-known theoretical quantum physics model in a synthetic material.

Novel Hardware Approach Produces a New Quantum Computing Paradigm

Department of Energy, Office of Science — Wed, 30 Oct 2024 13:00:43 EST

To run on a quantum computer, algorithms must be decomposed into a sequence of quantum gates, a difficult process. In this study, researchers developed a novel "hybrid" approach to quantum hardware design that replaces part of the quantum circuit with a physical evolution that relies on natural interactions within the system. This approach significantly reduces the complexity of executing quantum algorithms.
