A team of scientists from the U.S. Department of Energy’s Ames National Laboratory demonstrated a way to advance the role of quantum computing in materials research with an adaptive algorithm for simulating materials. Quantum computers have potential capabilities far beyond today’s computers, and using an adaptive algorithm allows them to produce solutions quickly and accurately.
Some things are related, others are not. Suppose you randomly select a person from a crowd who is significantly taller than the average. In that case, there is a good chance that they will also weigh more than the average.
Experts in nuclear physics and quantum information have demonstrated the application of a photon-number-resolving system to accurately resolve more than 100 photons. The feat is a major step forward in capability for quantum computing development efforts. It also may enable quantum generation of truly random numbers, a long-sought goal for developing unbreakable encryption techniques for applications in, for instance, military communications and financial transactions.
A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. It has the potential to significantly improve the imaging of nanostructures, including biological samples, and nanomaterial surfaces.
In APL Energy, researchers developed a proof of concept for a superconducting highway that could transport vehicles and electricity, cooling the necessary superconductors with a pipeline of liquid hydrogen. Most magnetic levitation designs feature the superconductor inside the vehicle, which is suspended above a magnetic track. The authors decided to flip that arrangement upside down, putting the superconductor on the ground and giving each vehicle a magnet. The result is a system with multiple uses, placing it within the realm of affordability.
A project led by a group of researchers from Israel's Bar-Ilan University, in collaboration with TII - the Quantum Research Center in Abu Dhabi, United Arab Emirates, is advancing quantum computing by improving the performance of superconducting qubits, the basic computation units of a superconducting quantum processor. The improved qubit, called a tunable superconducting flux qubit, is a micron-sized superconducting loop where electrical current can flow clockwise or counterclockwise, or in a quantum superposition of both directions.
Researcher will discuss the study which involved a sleeping aid known as suvorexant that is already approved by the Food and Drug Administration (FDA) for insomnia, hints at the potential of sleep medications to slow or stop the progression of Alzheimer’s disease.
The quantum computers of today grew out of this binary paradigm, but in fact the physical systems that encode their quantum bits (qubit) often have the potential to also encode quantum digits (qudits), as recently demonstrated by a team led by Martin Ringbauer at the Department of Experimental Physics at the University of Innsbruck.
Andrew Lupini, a scientist and inventor at the Department of Energy’s Oak Ridge National Laboratory, has been elected Fellow of the Microscopy Society of America.
The Argonne Quantum Foundry, a new scientific facility at Argonne, is meeting a critical need for quantum science by providing a robust supply chain of materials for quantum devices and systems.
A team of UCR electrical engineers and material scientists demonstrated a research breakthrough that may result in wide-ranging advancements in electrical, optical, and computer technologies.
The new field of quantum information science has been growing across the U.S. and around the globe, and now it has been developed for students and scholars to study at Middle Tennessee State University.
A study led by Oak Ridge National Laboratory researchers identifies a new potential application in quantum computing that could be part of the next computational revolution.
Supersolids are a relatively new and exciting area of research. They exhibit both solid and superfluid properties simultaneously.
Zhonghou Cai is the 2023 recipient of the Gopal K. Shenoy Excellence in Beamline Science Award. The annual award recognizes active beamline scientists at the Advanced Photon Source for significant contributions to research or instrumentation and support of the beamline user community.
Today’s electric vehicles can drive about 300 miles per charge. Lithium-sulfur batteries have the potential for a driving range of more than 400 miles with practical capacities of up to 500 watt-hours per kilogram at the pack level, twice that of lithium-ion batteries. That has made it a prime target for researchers.
Florida State University will dedicate more than $20 million to quantum science and engineering over the next three years, funding that will support hiring at least eight new faculty members, equipment and dedicated space in the university’s Interdisciplinary Research and Commercialization Building, and seed money for a new program focused on this emerging field. FSU President Richard McCullough announced the investments at the first day of the university’s Quantum Science and Engineering Symposium last week.
A team at the Advanced Quantum Testbed at Berkeley Lab (in collaboration with UC Berkeley and Yale) developed an architectural blueprint for a novel quantum processor based on fluxonium qubits, which outperform the most widely used superconducting qubits. Furthermore, they simulated two types of logic gates to validate the performance of the proposed fluxonium blueprint.
