Nanolaser on a chip could cut computer energy use in half

Researchers at DTU have developed a nanolaser that could be the key to much faster and much more energy-efficient computers, phones, and data centers. The technology offers the prospect of thousands of the new lasers being placed on a single microchip, thus opening a digital future where data is no longer transmitted using electrical signals, but using light particles, photons. The invention has been published in the journal Science Advances.

“The nanolaser opens up the possibility of creating a new generation of components that combine high performance with minimal size. This could be in information technology, for example, where ultra-small and energy-efficient lasers can reduce energy consumption in computers, or in the development of sensors for the health care sector, where the nanolaser’s extreme light concentration can deliver high-resolution images and ultrasensitive biosensors,” says DTU professor Jesper Mþrk, who co-authored the paper together with, among others, Drs. Meng Xiong and Yi Yu from DTU Electro.

ZeroDayRAT malware grants full access to Android, iOS devices

A new commercial mobile spyware platform dubbed ZeroDayRAT is being advertised to cybercriminals on Telegram as a tool that provides full remote control over compromised Android and iOS devices.

The malware provides buyers with a full-featured panel for managing infected devices, reportedly supporting Android 5 through 16 and iOS up to version 26 latest.

Researchers at mobile threat hunting company iVerify say that ZeroDayRAT not just steals data but also enables real-time surveillance and financial theft.

Topological antenna could pave the way for 6G networks

Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna capable of handling information-rich terahertz (THz) signals. Reporting their results in Nature Photonics, the team, led by Ranjan Singh at the University of Notre Dame, say that with further refinements, the design could help underpin future sixth-generation (6G) wireless networks, allowing data to be shared at unprecedented speeds.

In the not-too-distant future, 6G networks are expected to enable data rates of around one terabit per second—the same as transferring roughly half the storage of a mid-range smartphone in a single second. Achieving such speeds will require wireless systems to operate at terahertz frequencies, far higher than those used by today’s 5G networks.

However, before THz frequencies can be used reliably, major improvements are needed in the antennas that transmit and receive these signals.

Electron-phonon ‘surfing’ could help stabilize quantum hardware, nanowire tests suggest

That low-frequency fuzz that can bedevil cellphone calls has to do with how electrons move through and interact in materials at the smallest scale. The electronic flicker noise is often caused by interruptions in the flow of electrons by various scattering processes in the metals that conduct them.

The same sort of noise hampers the detecting powers of advanced sensors. It also creates hurdles for the development of quantum computers—devices expected to yield unbreakable cybersecurity, process large-scale calculations and simulate nature in ways that are currently impossible.

A much quieter, brighter future may be on the way for these technologies, thanks to a new study led by UCLA. The research team demonstrated prototype devices that, above a certain voltage, conducted electricity with lower noise than the normal flow of electrons.

Apple’s Historic Quarter Doesn’t Change the Need for AI Reckoning

Apple’s blockbuster holiday quarter was impressive — but it shouldn’t give cover to avoid an AI reckoning. Also: A new MacBook Pro is planned for the macOS 26.3 release cycle; the company explores a clamshell follow-up to its upcoming foldable phone; and an updated AirTag finally rolls out.

Last week in Power On: Inside Apple’s AI shake-up and its plans for two new versions of Siri powered by Gemini.

Quantis QRNG Chips

Quantum smartphone chip.

IDQ’s QRNG chip is available in six models, depending on size, performance, power consumption and certifications, in order to fit various industry-specific needs. All IDQ QRNG chips have received NIST Entropy Source Validation (ESV) certification on the independently and identically distributed (IID) entropy estimation track SP 800-90B.

ID Quantique is the first company to achieve an ESV certificate with a quantum entropy source and IID estimation track. Such randomness provides the most trusted random keys for encryption. Since October 2022 it has been mandatory for cryptographic modules aiming for FIPS 140–3 certification to have an ESV validated entropy source. This ESV IID Certificate #63 will also facilitate IDQ’s customers who integrate IDQ’s Chips into their own devices to go through the NIST’s Cryptographic Module Validation Program (CMVP).

Quantum mechanical effects help overcome a fundamental limitation of optical microscopy

Researchers from Regensburg and Birmingham have overcome a fundamental limitation of optical microscopy. With the help of quantum mechanical effects, they succeeded for the first time in performing optical measurements with atomic resolution. Their work is published in the journal Nano Letters.

From smartphone cameras to space telescopes, the desire to see ever finer detail has driven technological progress. Yet as we probe smaller and smaller length scales, we encounter a fundamental boundary set by light itself. Because light behaves as a wave, it cannot be focused arbitrarily sharply due to an effect called diffraction. As a result, conventional optical microscopes are unable to resolve structures much smaller than the wavelength of light, placing the very building blocks of matter beyond direct optical observation.

Now, researchers at the Regensburg Center for Ultrafast Nanoscopy, together with colleagues at the University of Birmingham, have found a novel way to overcome this limitation. Using standard continuous-wave lasers, they have achieved optical measurements at distances comparable to the spacing between individual atoms.
