Light-based Ising computer runs at room temperature and stays stable for hours

A team of researchers at Queen’s University has developed a powerful new kind of computing machine that uses light to take on complex problems such as protein folding (for drug discovery) and number partitioning (for cryptography). Built from off-the-shelf components, it also operates at room temperature and remains remarkably stable while performing billions of operations per second. The research was published in Nature.

The breakthrough shows that it is possible to build a practical and scalable machine that can tackle extremely difficult problems.

The project, led by Bhavin Shastri, Canada Research Chair in Neuromorphic Photonic Computing and professor in the Department of Physics, Engineering Physics, and Astronomy, with a team of his graduate students including Nayem Al Kayed and Hugh Morison, uses commercially available lasers, fiber optics, and modulators—the same technology that powers today’s internet infrastructure. The team partnered with McGill University researcher David Plant and his graduate student Charles St-Arnault.

Quantum Teleportation Was Performed Over The Internet For The First Time

Scientists achieved the ‘impossible’ in 2024, teleporting a quantum state through more than 30 kilometers amid a torrent of internet traffic.

In 2024, a quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.

The impressive demonstration by researchers in the US may not help you beam to work to beat the morning traffic, or download your favorite cat videos faster.

However, the ability to teleport quantum states through existing infrastructure represents a monumental step towards achieving a quantum-connected computing network, enhanced encryption, or powerful new methods of sensing.

Study finds ADHD symptoms linked to higher internet addiction risk in college students

A cross-sectional study of Chinese college students found ADHD symptoms were associated with internet addiction, with insomnia and executive dysfunction acting as mediating factors. Moderate and high physical activity levels were also linked with lower internet addiction symptoms, although causality cannot be inferred.

Ultra-thin metasurface can generate and direct quantum entanglement

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a variety of tasks. An ongoing quest within quantum engineering is the realization of a so-called quantum internet: a network conceptually analogous to today’s internet, in which distant nodes are linked through shared quantum resources, most notably quantum entanglement.

Researchers at Nanjing University and University of Science and Technology of China have developed a new ultra-thin metasurface that could contribute to this goal, as it can control the behavior of light, while also generating and directing entanglement across many channels.

This metasurface, presented in a paper published in Physical Review Letters, has so far proved to be promising for the development of scalable and integrated quantum technologies.

Researchers Warn: WiFi Could Become an Invisible Mass Surveillance System

Researchers say a new technology can identify individuals even when they are not carrying a WiFi device by passively recording signals in radio networks, raising serious privacy concerns and prompting calls for stronger protections. Walking past a café with an active WiFi network could be enough

Telecommunications beyond 6G: the first standalone spin-wave chip with a built-in magnetic field

Milan, 13th January 2025 — The Politecnico di Milano has created the first integrated and fully tunable device based on spin waves, opening up new possibilities for the telecommunications of the future, far beyond current 5G and 6G standards. The study, published in the journal Advanced Materials, was conducted by a research group led by Riccardo Bertacco of the Department of Physics of the Politecnico di Milano, in collaboration with Philipp Pirro of Rheinland-Pfälzische Technische Universität and Silvia Tacchi of Istituto Officina dei Materiali — CNR-IOM.

Magnonics is an emerging technology that uses spin waves – collective excitations of electronic spins in magnetic materials – as an alternative to electrical signals. The spread of this technology has been restricted until now by the need for an external magnetic field, which has prevented it being incorporated into chips.

The new device developed at the Politecnico overcomes this hurdle: it is miniaturised (100 × 150 square micrometres, so much smaller than current radiofrequency signal processing devices based on acoustic waves); it is fully integrated on silicon – and therefore compatible with existing electronic platforms, and it functions without external magnets, thanks to an innovative combination of permanent SmCo micromagnets and magnetic flux concentrators.

Emerging Technology Convergence Will Shape Our Future

The future won’t be built on one breakthrough. It will be shaped by how well we mesh AI, quantum, 5G, IoT, and human intelligence into secure, resilient systems. Technology advantage now comes from orchestration, not adoption.

My latest Forbes article explores why this convergence will define the next decade.

The next decade of innovation will not be defined by a single breakthrough technology. Instead, it will be shaped by the convergence of multiple emerging technologies.
