Chinese researcher Yin Juan, a member of the QUESS team who received the annual Newcomb Cleveland Prize, said China’s satellite Quantum Experiments at Space Scale (QUESS) or Micius would work at least two more years beyond its two-year working lifetime and carry out more international cooperation. In the next two years, the QUESS team is expected to have the inter-continental quantum key distribution (QKD) experiments with those from Italy, Russia and South Korea.
Based on the QKD technology, Chinese researchers could launch three more small-size satellites in the next three to five years to form a network that can fulfill more quantum communication tasks, a critical step to create the infrastructure of a globalized quantum internet one day, said Yin.
