In search of the theory of gravity
As new and powerful telescopes gather new data about the universe, they reveal the limits of older theories. Credit: Shutterstock Einstein’s theory of gravity—general relativity—has been very successful for more…
Can cloud-based quantum computing really offer a quantum advantage?
The input to the service is a user-designed quantum circuit. The service begins with qubit allocation, which relates physical qubits to a designed circuit. An implementation of the circuit is…
How Radio Astronomy Sees Magnetic Fields
Newswise — Many objects in the Universe have magnetic fields. Planets such as Earth and Jupiter, the Sun and other stars, even galaxies billions of light years away. But these…
Quiet cables set to help reveal rare physics events
PNNL chemist Isaac Arnquist examines ultra-low radiation copper cables specially created for sensitive physics detection experiments. Credit: Andrea Starr | Pacific Northwest National Laboratory Imagine trying to tune a radio…
A model probing the connection between entangled particles and wormholes in general relativity
This shows the simulation, or time evolution, of the system. t-bar is a unitless time variable. The blue curve illustrates the wormhole. The horizontal portion is the main part of…
Researchers advance topological superconductors for quantum computing
As part of the Quantum Science Center headquartered at ORNL, Robert Moore probes the interface between a topological insulator and a superconductor with spin- and angle-resolved photoemission spectroscopy. Credit: Carlos…
LCLS-II ushers in a new era of science
The newly upgraded Linac Coherent Light Source (LCLS) X-ray free-electron laser (XFEL) at the Department of Energy’s SLAC National Accelerator Laboratory successfully produced its first X-rays. The upgrade, called LCLS-II,…
