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.

Los Alamos Forms Quantum Computing-Focused Research Center

PRESS RELEASE — Los Alamos National Laboratory has formed the Center for Quantum Computing, which will bring together the Lab’s diverse quantum computing research capabilities. Headquartered in downtown Los Alamos, the Center for Quantum Computing will consolidate the Laboratory’s expertise in national security applications, quantum algorithms, quantum computer science and workforce development in a shared research space.

“This new center of excellence will bring together the Laboratory’s quantum computing research capabilities that support Department of Energy, Defense and New Mexico state initiatives to achieve a critical mass of expertise greater than the individual parts,” said Mark Chadwick, associate Laboratory director for Simulation, Computing and Theory. “This development highlights our commitment to supporting the next generation of U.S. scientific and technological innovation in quantum computing, especially as the technology can support key Los Alamos missions.”

The center will bring together as many as three dozen quantum researchers from across the Lab. The center’s formation occurs at a pivotal time for the development of quantum computing, as Lab researchers partner with private industry and on a number of state and federal quantum computing initiatives to bring this high-priority technology closer to fruition. Laboratory researchers may include those working with the DARPA Quantum Benchmarking Initiative, the DOE’s Quantum Science Center, the National Nuclear Security Administration Advanced Simulation and Computing program’s Beyond Moore’s Law project, and multiple Laboratory Directed Research and Development projects.

New type of magnetism discovered in 2D materials to help store data

Researchers have discovered a new type of magnetism in 2D materials that can help store data.

The team led by researchers from the University of Stuttgart experimentally demonstrated the previously unknown form of magnetism in atomically thin material layers.

Researchers revealed that the discovery is highly relevant for future magnetic data storage technologies and advances the fundamental understanding of magnetic interactions in two-dimensional systems.

This paper-thin chip turns invisible light into a steerable beam

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus-control problem in light-shaping materials. This opens the door to tiny, highly efficient light sources integrated directly onto chips.

Computer simulations reveal hurricane currents can knock down surface wave heights

Using advanced computer simulations, researchers from the University of Rhode Island’s Graduate School of Oceanography (GSO) have concluded how and why strong ocean currents modify surface waves. “Our primary finding is that hurricane-generated ocean currents can substantially reduce both the height and the dominant period of hurricane waves,” said Isaac Ginis, URI professor of oceanography. “The magnitude of wave reduction depends strongly on how accurately ocean currents are predicted. This highlights the importance of using fully coupled wave-ocean models when forecasting hurricane waves.”

Ginis conducted the research with URI Professor Tetsu Hara and Angelos Papandreou, who earned his Ph.D. in oceanography from URI in December 2025. Their results were published in a peer-reviewed article in the Journal of Physical Oceanography in January 2026.

According to Ginis, waves are most strongly reduced by currents on the front right of the storm, where winds, waves, and currents are typically strongest.

This C Engine’s ECS Reportedly Outperforms Unity’s DOTS

Gabriel Dechichi, a developer you might remember from his challenge of making an Unreal Engine game in 4 weeks, has demonstrated his ECS system in C, claiming it runs roughly 17 times faster than Unity’s DOTS.

According to Gabriel, the simulation runs 100,000 boids, rendering around 31 million triangles per frame. The average simulation time is about 2.4 ms in the C engine, compared to around 44.4 ms in Unity’s ECS. The test was conducted on an AMD Ryzen 7 5800H (8 cores, 16 threads) with an NVIDIA GeForce RTX 3,060 Laptop GPU and 32 GB of RAM, running in Chrome with force-high-performance-GPU enabled.

“Frame time difference is about 5 times, as the demo is GPU-bound. The ECS simulation runs at roughly 2.4ms on my C engine, vs roughly 44.4 ms for Unity ECS. Time is measured equally on both demos by sampling how long the ECS world takes to update,” shared the developer.

PRISM reanalyzes 4,400 tumors, reshaping the debate over tumor microbiomes

When scientists sequence tumor DNA, they typically find small amounts of genetic code from bacteria, viruses and fungi—microorganisms that—if actually present in tumor tissues—could influence how they grow, evade immunity or respond to treatment. But do microorganisms truly reside in tumors, or do the samples become contaminated before sequencing occurs?

Independent analyses of the same genomic data have reached wildly different conclusions. Now, researchers at Rutgers Cancer Institute have developed a computational tool that settles the controversy by distinguishing genuine microbial signals from artifacts. Their findings are published in Cancer Cell.

“There are microbes all over the environment, on our skin and in our breath,” said Subhajyoti De, a member of the Genomic Instability and Cancer Genetics Program at Rutgers Cancer Institute and the senior author of the study. “There could be DNA particles floating in the air. How do you know whether you’re finding came from the tissue you were interested in, or whether something was introduced along the way?”

Quantum defects in carbon nanotubes as single-photon sources

This Review surveys progress in the development of carbon nanotubes as single-photon sources for emerging quantum technologies, with a focus on chemical synthesis and quantum defect engineering, computational studies of structure-property relationships, and experimental investigations of quantum optical properties.

GeSn alloys emerge as a new semiconductor class that could reshape optoelectronics

Scientists have created a new type of material that could enable common electronic devices to work faster and use less energy, a study suggests. The findings indicate the material, which was until now thought near-impossible to make, can act as a highly effective semiconductor—a key component of modern electrical devices.

Using the new semiconductor in electronics such as computer processors or medical imaging devices could help them run more efficiently, the team says.
