"transmitted single photons/ entangled photon pairs 13 miles through open atmosphere, using adaptive optics with high-frequency deformable mirrors, compensating for atmospheric turbulence... wireless connection plugs directly into existing fiber-optic quantum network, eliminating need for wavelength conversion required by standard optical cables... future: extend this free-space capability across 30 miles of open water to connect with a partner facility"
