On-chip laser frequency combs — lasers that emit multiple frequencies or colors of light simultaneously separated like the tooth on a comb — are a promising technology for a range of applications including environmental monitoring, optical computing, astronomy, and metrology. However, these are still limited by one serious problem — they are not always efficient. ...
Having enough RAM is important for your laptop’s fast performance and responsiveness. RAM (Random Access Memory) is your computer’s temporary storage. And when you open many applications or several browser tabs, your RAM stores data that you need to retrieve quickly. You probably know that more intensive laptop applications need more RAM. But does your ...
An international team from Delft, Lancaster, Nijmegen, Kyiv, and Salerno has demonstrated a new technique to generate spin waves that propagate through the material at a speed much faster than the speed of sound. These so-called spin waves produce a lot less heat than conventional electric currents, making them promising candidates for future computation devices ...
A team of physicists from the Harvard-MIT Center for Ultracold Atoms, along with other universities, have taken a big step by developing a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or “qubits.” The system marks a major step toward building large-scale quantum machines that ...
Worcester Polytechnic Institute (WPI) security researchers Berk Sunar and Daniel Moghimi led an international team of researchers that discovered serious security vulnerabilities in computer chips made by Intel Corp. and STMicroelectronics. The flaws affect billions of laptop, server, tablet, and desktop users around the world. The proof-of-concept attack is dubbed TPM-Fail. The two newly found ...
Big U.S. tech companies like Microsoft, Dell, and HP are reportedly looking to transfer a good chunk of their manufacturing out of China due to the sour trade relationship between Beijing and Washington. Moving out production “Hardware production has long been centered on China where production costs are cheaper, components of the tech supply chain ...
