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." It was found that polarization drift was both wavelength- and time-dependent, requiring Qunnect to design and build equipment for active compensation at the same wavelengths... Qunnect's GothamQ loop demonstration was especially noteworthy for its duration, the hands-off nature of the operation time, and its uptime percentage.
