Quantum Internet Proves Real-World Feasibility Across 38 Miles of Fiber

NIST researchers transmitted polarization-entangled photons across 62 kilometers (38.5 miles) of existing, above-ground fiber in real-world conditions, maintaining entanglement despite environmental noise by using a laser reference to calibrate corrections. The setup operated with 200–1,500 entangled photons per second, showing feasibility for practical quantum networks and potential uses in quantum-secure communications and distributed telescopes, though faster hardware and better software are needed for a full quantum internet.

Brazen fiber sabotage cuts 1,400 cables, triggering Spectrum outages in Central LA

Vandals severed more than 1,400 fiber-optic cables in Baldwin Hills, causing Spectrum internet and mobile outages across Beverly Hills, West Hollywood and Koreatown; Verizon experienced similar attacks in Southern California. Repairs are underway, Spectrum is offering up to $25,000 for information, and the motive remains unknown as authorities warn such infrastructure damage threatens public safety.

Georgetown hit by 20,000-user internet outage after cable attack

Georgetown experienced a large internet outage after criminals damaged Optimum’s fiber network near I-35 and Northwest Boulevard, affecting about 20,000 customers (including some T-Mobile users) and causing more than $100,000 in damages. Police are reviewing surveillance to identify those responsible, and Optimum says the incident is part of a broader trend of thieves targeting telecom infrastructure—even though the fiber lines themselves don’t contain copper. Restoration is underway, but no timeline has been provided, and officials caution outages can impact essential services like 911; residents are urged to report suspicious activity.

Earth gravity bends light to boost remote sensing

Australian physicist Enbang Li has built a compact, three‑foot device that uses gravity to bend light via spiraled fiber-optic coils, detecting tiny picosecond time delays to sense gravitational changes. The approach could enable high‑precision gravity sensing for mapping underground features, monitoring magma, and improving sensing on moving platforms like planes and submarines. While still in early lab stages, the work suggests photons can interact with Earth’s gravitational field in new ways and may prompt fresh thinking about light’s behavior, with findings published in Scientific Reports.

First fiber‑optic FPV drone reaches Kharkiv, prosecutors say

Ukraine’s Kharkiv region reports a Russian FPV drone reached the city via a fiber‑optic cable for the first time since the full‑scale invasion. The drone hit a tree in the Kyivskyi district around 3 p.m. on Feb. 25; no casualties were reported, and the Kharkiv regional prosecutor’s office opened a pre‑trial investigation. Fiber‑optic FPV drones extend range and can evade electronic warfare, with countermeasures mainly limited to physical destruction or obstruction; Kharkiv’s proximity to Russian‑occupied areas makes this development notable in the evolving drone warfare.

Scientists Advance Quantum Communication with Long-Distance Photonic Highway and Secure Protocols

Researchers at the University of Rochester and RIT have developed the Rochester Quantum Network (RoQNET), an 11-mile-long quantum communication system using photons transmitted over fiber-optic cables, which could enhance secure communications and enable new quantum technologies. The system leverages integrated photonic chips and aims to connect various research facilities, advancing scalable and cost-effective quantum networking.

"Breakthrough: Researchers Achieve Fiber Optic Connection 1.2 Million Times Faster Than Broadband"

Researchers at UK's Aston University have achieved a data transfer rate of 301 terabits per second using a single fiber optic cable, which is 1.2 million times faster than the average American broadband connection. By accessing new wavelength bands normally unreachable in existing optical fibers, the team utilized an optical processor to access the never-before-used E- and S-bands, achieving these speeds without the need for new, high-tech fiber optic lines. This breakthrough could potentially allow internet providers to significantly increase standard speeds without overhauling current fiber optic infrastructures.
