Drones to create local quantum networks
A team of Chinese researchers has used drones to create a prototype of a small airborne quantum network and to send entangled particles from one drone to another and from a drone to the ground.
New Quantum Random Number Generation improvement
A research team from the University of Science and Technology of China has made security analysis and improvement of Source Independent Quantum Random Number Generators (SI-QRNGs) with imperfect devices. By studying the actual characteristics of
High-dimensional quantum teleportation
A team at the University of Science and Technology of China (USTC) has demonstrated the teleportation of high-dimensional states in a three-dimensional six-photon system. Compared with two-dimensional systems, high-dimensional system quantum networks have the advantages
Better security proofs for QKD protocols
Quantum Key Distribution (QKD) protocols are performed by sending a sizeable, but finite, number of quantum signals between the distant parties involved. Many QKD experiments, however, predict their achievable key rates using asymptotic formulas, which
China: World’s first integrated quantum communication network
Chinese scientists have established the world’s first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve Quantum Key Distribution (QKD) over a total distance of 4,600
Securing a wireless link with MDI-QKD
Relying in part on techniques used to sharpen up images from ground-based telescopes, researchers in China have implemented a type of secure quantum communications protocol—known as measurement-device-independent quantum key distribution (MDI-QKD)—across a wireless link connecting
Quantum teleportation with 90% accuracy over 44 km
Researchers at California Institute of Technology have achieved conditional quantum teleportation of time-bin qubits at the telecommunication wavelength of 1536.5 nm. They measured teleportation fidelities of ≥ 90% that are consistent with an analytical model
