Terahertz-frequency communications promise ultra-high data rates and stable latency, yet current systems lag behind infrared technologies. Here, the authors demonstrate a pioneering multi-gigabit-per-second free-space optical communication using a terahertz quantum cascade laser, setting the stage for advanced wireless networks with significant implications for high-speed data transmission.
