Insider Brief Researchers demonstrated quantum key distribution across an 18-kilometer free-space link by using adaptive optics to counter atmospheric turbulence and connect the signal to conventional fiber infrastructure. The field trial in northeastern Italy generated secret encryption keys at an average rate of about 1,000 bits per second with high-efficiency superconducting detectors and 200 bits […]
