Quantum Internet Prototype Runs For 15 Days Under New York City

Under the streets of New York City, they're testing a "quantum network," reports Phys.org — where engineers from a Brooklyn company named Qunnect Inc are taking steps to "overcome the fragility of entangled states in a fiber cable and ensure the efficiency of signal delivery."For their prototype network, the Qunnect researchers used a leased 34-kilometer-long fiber circuit they called the GothamQ loop. Using polarization-entangled photons, they operated the loop for 15 continuous days, ach
