The electronic and optical devices that we use on a daily basis, such as mobile phones, LEDs and solar cells use transistors and other parts that are consistently getting smaller and more compact. With an ever-growing need ...
The precise control of micro-mechanical oscillators is fundamental to many contemporary technologies, from sensing and timing to radiofrequency filters in smartphones. Over the past decade, quantum control of mechanical systems ...
Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel (CrCoNi). Not only is the metal extremely ductile—which, in materials ...
Unlike in humans, when computer "brains" evolve, they get smaller and smaller. This is because the components that perform calculations and consolidate stored information work more efficiently when there are more of them ...
In a scene from "Star Wars: Episode IV—A New Hope," R2D2 projects a three-dimensional hologram of Princess Leia making a desperate plea for help. That scene, filmed more than 45 years ago, involved a bit of movie magic—even ...
Quantum memory devices can store data as quantum states instead of binary states, as classical computer memories do. While some existing quantum memory technologies have achieved highly promising results, several challenges ...
Silicon, an element abundant in Earth's crust, is currently the most widely used semiconductor material and is important in fields like engineering, geophysics and plasma physics. But despite decades of studies, how the material ...
With their superior efficiency, stability, and device volume properties, conventional light emitting diodes (LEDs) have already revolutionized the lighting and display world. LEDs are typically stacks of semiconductor thin ...
The amount of energy used for computing is climbing at an exponential rate. Business intelligence and consulting firm Enerdata reports that information, communication and technology accounts for 5% to 9% of total electricity ...
Jennifer Choy makes atom-size antennas. They bear no resemblance to the telescoping rod that transmits pop hits through a portable stereo. But functionally, they're similar. They're quantum sensors, picking up tiny electromagnetic ...
