A New Design for Quantum Computer–Monitored Electrical Grids

With support from the Quantum Computer User Program (QCUP) at the Oak Ridge Leadership Computing Facility (OLCF), researchers from Cornell University have developed a new quantum computer–based artificial intelligence (AI) system for identifying and diagnosing faults in electrical power grids. The framework promises much faster response times and smarter solutions…

Quantum computing enables simulations to unravel mysteries of magnetic materials

A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other practical techniques. Researchers from the Department of Energy’s Oak Ridge National Laboratory; the University of Tennessee, Knoxville; Purdue University and D-Wave Systems…

Developing a Quantum Community

In April, the Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy (DOE) Office of Science User Facility located at DOE’s Oak Ridge National Laboratory (ORNL), held its second Quantum Computing User Forum. The virtual event welcomed nearly 200 attendees from around the world and featured a series…

Quantum Processors are Now Challenging Conventional HPC Systems

To prove quantum supremacy, a joint research team from Google Inc., NASA Ames Research Center, and the Department of Energy’s Oak Ridge National Laboratory (ORNL), needed to rule out that classical supercomputers could perform computational tasks at the same speed as Google’s Sycamore quantum computer. So, they came to the…

Another First for Quantum

The beginnings of quantum computing bring about many firsts. In 2010 a team led by B. P. Lanyon simulated a hydrogen molecule, H2, on a quantum system for the first time. Last fall research scientists at IBM performed the first quantum calculations of molecules beyond hydrogen and helium. Now a…
