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 […]
