Scientists have advanced quantum teleportation by mitigating noise interference through a novel method involving hybrid entanglement, achieving close to 90% fidelity in teleporting quantum states, which could significantly enhance secure quantum communication.
A research team led by Academician Guangcan Guo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), in collaboration with the research team at the University of Turku, Finland, successfully overcame environmental noise to achieve high-fidelity quantum teleportation by utilizing multipartite hybrid entanglement. Their findings were published recently in the journal
