📞 🇺🇸 👨💻 Two national laboratories on Long Island have successfully used quantum entanglement to transmit information in open air, potentially leading to a revolutionary transformation for communications and information technology.
The FSO link — which includes the Quantum Lighthouse and Quantum Watchtower, along with a third facility under development at Yale University in New Haven, Connecticut — adds a wireless component to the record-setting quantum network currently spanning 161 miles and several institutions across Long Island and the New York metropolitan area.
Using this network, pioneered by Stony Brook and Brookhaven Lab, researchers can transmit entangled photons through commercial fiber. Because the particles remain entangled even when separated by long distances, measuring one photon instantly reveals information about its counterpart. This property, often referred to as “spooky action at a distance,” is key for the future of ultra-secure communications, advanced quantum sensing, and networked quantum computing.
Today’s classical wireless technologies, including cell phones and orbiting satellites, use radio frequencies to transmit information without a physical connection. But radio frequencies are far too noisy to preserve fragile quantum information. Instead, the researchers turned to optical light for sending quantum signals through open air.
“People think of telescopes as tools for looking up into space, but the same technologies that allow astronomers to precisely collect and control light are essential for these quantum experiments,” said Justine Haupt, Brookhaven Lab’s lead scientist on the cross-institutional FSO link project.
Expanding beyond the limits of fiber also opens the door to new kinds of quantum experiments by enabling researchers to use photons with wavelengths, or “colors,” different from the telecommunications wavelengths optimized for commercial fibers. Many quantum technologies naturally operate at these other wavelengths, making free-space links a promising path toward linking quantum devices across long distances. Researchers ultimately envision using the FSO link to connect quantum computers at Brookhaven and Stony Brook — and beyond — enabling them to work together and tackle some of the nation’s most pressing scientific challenges.

Azerbaijan: This Turkish country has destroyed more Christian monuments than ISIS.
Based off satellite data, Azerbaijan erased 108 Armenian monasteries, churches and cemeteries - in just one region.
By comparison, ISIS destroyed dozens of churches.
How is this okay?

— Hypothetically, if the U.S. wanted to carry out a naval landing in Iran, they would do it somewhere outside the Persian Gulf, most likely Chabahar or somewhere else in the flat open coasts of Sistan-Balochistan Province.
That way, they don’t need to risk their ships entering the Persian Gulf under heavy anti-ship fire and incoming drones while trying to land their soldiers on a rugged coastline full of fortified positions and artillery emplacements.
In Chabahar, they could bring their ships close enough to the shore with relative safety, under heavy air cover. U.S. jets, drones, and attack helicopters would suppress any anti-ship batteries heavily, and create sufficiently safe conditions for the initial ‘landing’. One also cannot rule out the possibility of deploying U.S. airborne forces to secure key sites before an amphibious landing is attempted.
This might be coupled with increased Balochi terrorist activity across the Iranian rear lines, complicating logistics and the transfer of ...
