Video PlayerClose HEFEI, Feb. 13 (Xinhua) — A Chinese research team has realized entanglement of two quantum memories via fibers over 50 km, making a breakthrough in the field of quantum communication. Quantum entanglement is a quantum mechanical phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects may be spatially separated. The successful experiment has laid the foundation for the development of a quantum internet that should enable a number of revolutionary applications such as distributed quantum computing. The experiment was jointly conducted by researchers with the University of Science and Technology of China (USTC), Jinan Institute of Quantum Technology, and Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences. The researchers in the experiment with USTC include Pan Jianwei, often dubbed the “Father of Quantum” in China, Bao Xiaohui, and Zhang Qiang. “Despite enormous progress, at present, the maximal physical separation achieved between two nodes is 1.3 km, and challenges for longer distances remain,” the researchers wrote in a paper published Wednesday in the journal Nature. “Our experiment could be extended to nodes physically separated by similar distances, which… Read full this story
