Quantum signals escape fiber, travel 13 miles in open air in New York

Quantum signals have broken free from their fiber-optic constraints, traveling 13 miles in open air across New York. This development challenges the conventional understanding of quantum communication, which has traditionally relied on fiber-optic cables to transmit signals.

The breakthrough was achieved by researchers at Stony Brook University and Brookhaven National Laboratory, who demonstrated the ability to send quantum signals wirelessly. The experiment, detailed in coverage from The South Shore Press, Newswise, Newsday, SBU News and Interesting Engineering, marks a significant step forward in quantum network expansion.

The next steps involve scaling this technology and integrating it into existing quantum networks. The researchers have not yet disclosed the specific methods used to achieve this wireless transmission, leaving open the question of how this technology can be replicated and improved.
