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…

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,…

Buried Ancient Roman Glass Formed Substance with Modern Applications

Newswise — Some 2,000 years ago in ancient Rome, glass vessels carrying wine or water, or perhaps an exotic perfumes, tumble from a table in a marketplace, and shatter to…
