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…
Quiet cables set to help reveal rare physics events

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,…
ATLAS experiment places some of the tightest limits yet on magnetic monopoles
Illustration of magnetic monopoles (larger image) and a magnetic dipole (inset). Credit: CERN Magnets, those everyday objects we stick to our fridges, all share a unique characteristic: they always have…
