“State-of-the-art quantum devices are not yet large enough to be called full-scale computers. The biggest comprise just a few dozen qubits—a meager count compared to the billions of bits in an ordinary computer’s memory. But steady progress means …
“A team of researchers from the University of Maryland, the Army Research Laboratory and Argonne National Laboratory (U.S. Department of Energy) has published findings on a new advanced battery technology that among its many possible applications has the potential …
“Transistors are tiny switches that form the bedrock of modern computing—billions of them route electrical signals around inside a smartphone, for instance. Quantum computers will need analogous hardware to manipulate quantum information. But the design constraints for this new …
“A team of researchers from the University of Maryland’s A. James Clark School of Engineering have created a water-based zinc battery that is simultaneously powerful, rechargeable, and intrinsically safe. The new aqueous zinc battery could eventually be used in …
“Exotic physics can happen when quantum particles come together and talk to each other. Understanding such processes is challenging for scientists, because the particle interactions can be hard to glimpse and even harder to control. Moreover, modern computer simulations struggle …
“Optical highways for light are at the heart of modern communications. But when it comes to guiding individual blips of light called photons, reliable transit is far less common. Now, a collaboration of researchers from the Joint Quantum Institute (JQI …
“A chemical bath and a hot-press can transform wood into a material that is stronger than steel, researchers report. The process, and others like it, could make the humble material an eco-friendly alternative to using plastics and metals in the …
“Machine learning, the field that’s driving a revolution in artificial intelligence, has cemented its role in modern technology. Its tools and techniques have led to rapid improvements in everything from self-driving cars and speech recognition to the digital mastery …
“The U.S. Department of Energy (DOE) is joining the quest to develop quantum computers, devices that would exploit quantum mechanics to crack problems that overwhelm conventional computers. The initiative comes as Google and other companies race to build a …
“Searching large, unordered databases for a desired item is a time-consuming task for classical computers, but quantum computers are expected to perform these searches much more quickly. Previous research has shown that Grover’s search algorithm, proposed in 1996, is …
“Technique uses the power of artificial neural networks to address several types of flaws and degradations in a single image at once From phone camera snapshots to lifesaving medical scans, digital images play an important role in the way humans …
“Christopher Monroe spends his life poking at atoms with light. He arranges them into rings and chains and then massages them with lasers to explore their properties and make basic quantum computers. Last year, he decided to try something seemingly …
“JQI scientists have achieved a major milestone in simulating the dynamics of condensed-matter systems – such as the behavior of charged particles in semiconductors and other materials – through manipulation of carefully controlled quantum-mechanical models. Going beyond their pioneering experiments in 2009 …
