One of the most striking revelations was that spies had tapped into fiber-optic cables to monitor the vast amounts of information flowing through them. Snowden’s revelations have spurred efforts to tap the almost mystical properties of quantum science to make such hacking impossible. Now there are signs of progress. A startup called Quantum Xchange says it has struck a deal giving it access to […]
