submeta writes "Researchers in Munich have successfully performed a quantum key exchange between a moving aircraft and a ground station. Quantum key distribution, which exploits the phenomenon of entanglement, offers theoretically perfect encryption (although it can be vulnerable in practice). This advance is an important step on the way to key exchange with a satellite, which could enable practical usage of the technology."
