British, Norwegian and American maritime forces confronted Russian vessels preparing to undertake an exercise to test a new device for cutting undersea fiber optic cables.

The confrontation happened near Svalbard, (north of Norway/Sweden and east of Greenland) where two fiber-optic cables extend for about 1,400km and are ~2,700 meters underwater.

Those lines support data transfers from SvalSat, a major satellite ground facility that also serves NASA’s Near Space Network in orbit. https://www.techradar.com/pro/nato-prevented-russia-from-cutting-a-critical-undersea-cable-using-a-tool-that-leaves-no-traceable-fingerprints-on-fibre-optic-wires-1-400km-long-lines-are-part-of-nasas-near-space-network #FibreOptics #UnderSeaCables #Russia #NATO #NASA #SatelliteData #SvalSat #Data #Britain #Norway #USA

Weekend Reading! Check out his TechAptitude post on the upcoming Quantum Internet.

One of the first tangible outcomes from Quantum Technologies will likey be a highly -secure global communications backbone, a “quantum internet”, that could connect data centers, financial institutions, government facilities, with unbreakable encryption and quantum level security. https://techaptitude.substack.com/p/quantum-repeaters-bring-on-the-quantum #Quantum #QuantumInternet #QuantumTechnologies #Communications #Internet #Security #Encryption #QuantumRepeater #Photons #FibreOptics

NIST and University of Colorado researchers demonstrated over 99% effectiveness in transmitting photons over a 2 km link of standard optical fiber. The team successfully separated the signals needed for fiber stabilization, trillions of photons per second, from the single photons carrying quantum information, overcoming a significant technical hurdle.

Net-net the experiment illustrated strong separation between the classical light signals and the quantum signals transversing fiber optic cables dramatically reducing sources of error and noise for optic based quantum systems.

Canadian start up Xanadu (founded in 2016) went IPO via SPAC (Mar 27) on the Nasdaq and TSX stock exchanges under the ticker symbol "XNDU".

Xanadu is building photonics-based quantum computing systems and claims its approach can leverage existing modern chip manufacturing facilities and optical components like fibre optics. https://www.xanadu.ai/press/xanadu-becomes-first-pure-play-photonic-quantum-computing-company-to-go-public #Quantum #QuantumComputing #Xanadu #TSX #NASDAQ #IPO #Photonics #SPAC #Optics #FibreOptics

🔆 What's faster than light speed? Well, it's still light speed, but in terms of an optical fibre, UK researchers say transmitting the light through a hollow core fibre would be able to speed up data transmissions by 45%, and let it travel further without needing a little boost

European telcos and US tech giants are having a row over 5G and fibre broadband. The telcos say they need more money and big tech should help pay for internet access, since they make money off it.

Big tech says charging both consumers and content providers is against net neutrality. However some analysts think it's just two very powerful parties fighting about money and that the telcos are lying. So who's right?
