In a groundbreaking feat, scientists from the Zihuishan Observatory of the Chinese Academy of Sciences have successfully transmitted high-definition video signals over a distance of 1.2 kilometers using superconducting reception technology at the sub-millimeter wave astronomical observation base in Qinghai Province. This marks the world’s first application of terahertz (THz) communication technology in a long-distance wireless transmission system above the 0.5 THz band, setting an international benchmark in future communication advancements.
Terahertz communication, known as the “Xinjiang” of future technologies, operates in the spectrum between microwaves and light waves, offering unparalleled penetration and an ultra-wide bandwidth. Imagine increasing a two-lane highway to eight lanes—that’s the bandwidth potential this technology brings! Overcoming the notorious signal attenuation challenges of THz communication, the research team achieved this milestone with an impressively low signal transmission intensity of just 10 mW—equivalent to one-millionth the power of a mobile base station. Conducted at an altitude exceeding 4,000 meters, this success not only underscores China’s leadership in superconducting detector technology but also paves the way for innovative applications across space communication, astronomy, medical imaging, and beyond.
Li Jing, a lead researcher, likened the impact of THz communication to a revolution in connectivity. This experiment demonstrates that THz technology, with its incredible sensitivity and low signal loss, has the potential to transform industries ranging from telemedicine to safety monitoring. With nearly three decades of pioneering research culminating in this achievement, China has positioned itself at the forefront of global advancements in communication technology, promising revolutionary changes for both science and everyday life.
