The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence ...

Terahertz-frequency (THz) carrier waves in free-space optical (FSO) communications offer the potential for > 1 Tbit/s data rates and stable latency. They offer wider bandwidths than available in the ...

In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...

Free-space optical communication with high transmission bandwidth and small antenna size has been progressively deployed for ground-air-space communications in recent years. However, current ...

Scientists used a new invariant property of vectorial light to encode information. This quantity, which the team call 'vectorness', scales from 0 to 1 and remains unchanged when passing through a ...
