Research Triangle Park, N.C. — A U.S. Army research result brings the quantum internet a step closer. Such an internet could offer the military security, sensing, and timekeeping capabilities not possible with traditional networking approaches.

The U.S. Army’s Combat Capability Development’s Army Research Laboratory’s Center for Distributed Quantum Information, funded and managed by the lab’s Army Research Office, saw researchers at the University of Innsbruck achieve a record for the transfer of quantum entanglement between matter and light — a distance of 50 kilometers using fiber optic cables.

Entanglement is a correlation that can be created between quantum entities such as qubits. When two qubits are entangled and a measurement is made on one, it will affect the outcome of a measurement made on the other, even if that second qubit is physically far away.

Having a slow connection is always frustrating, but just imagine how supercomputers feel. All those cores doing all kinds of processing at lightning speed, but in the end they’re all waiting on an outdated network interface to stay in sync. DARPA doesn’t like it. So DARPA wants to change it — specifically by making a new network interface a hundred times faster.

The problem is this. As DARPA estimates it, processors and memory on a computer or server can in a general sense work at a speed of roughly 10¹⁴ bits per second — that’s comfortably into the terabit region — and networking hardware like switches and fiber are capable of about the same.

“The true bottleneck for processor throughput is the network interface used to connect a machine to an external network, such as an Ethernet, therefore severely limiting a processor’s data ingest capability,” explained DARPA’s Jonathan Smith in a news post by the agency about the project.

Last year, Princeton researchers identified a disturbing security flaw in which hackers could someday exploit internet-connected appliances to wreak havoc on the electrical grid. Now, the same research team has released algorithms to make the grid more resilient to such attacks.

In a paper published online in the journal IEEE Transactions on Network Science and Engineering, a team from Princeton’s Department of Electrical Engineering presented algorithms to protect against potential attacks that would spike demand from high-wattage devices such as air conditioners—all part of the “internet of things”—in an effort to overload the power grid.

“The cyberphysical nature of the grid makes this threat very important to counter, because a large-scale blackout can have very critical consequences,” said study author Prateek Mittal, an associate professor of electrical engineering.

What could we do to stop our Sun from eventually expanding and burning out? In this Cosmic Query, astrophysicist Neil deGrasse Tyson explains how we can prolong the life of a star. Co-host Chuck Nice offers his sci-fi option for Earth’s future.

This is the final part in a series of in-depth articles examining China’s efforts to build a stronger domestic semiconductor industry amid rising trade tensions.

Some in China see custom AI chips, which can offer superior performance to conventional integrated circuits even when manufactured using older processes, as helping the country loosen its dependence on the US in core technology.

Wi-Fi 6 certification is here. On Monday, an announcement from the Wi-Fi Alliance datelined Austin, Texas said the Wi-Fi CERTIFIED 6 certification program from Wi-Fi Alliance was now available.

Edgar Figueroa, president and CEO, Wi-Fi Alliance, said, “Wi-Fi CERTIFIED 6 will deliver improvements in connectivity, including in high density locations and IoT environments.”

(Standards for Wi-Fi are established by the Institute of Electrical and Electronic Engineers, and devices are certified for these new standards by the Wi-Fi Alliance, said Lauren Goode in Wired.)

Financial analysts are looking at Elon Musk’s plans to surround Earth with thousands of high-speed internet satellites — and they see a lot of green.
