  1. Advances in quantum cryptography could enable the creation of a global quantum Internet. It would consist of networks on the ground, as well as in space, set up via satellites capable of exchanging photons in fragile quantum states. Image courtesy of Shutterstock/Login.

  2. Fifteen seconds after it launched in 2014, this Antares rocket exploded, showering the shore and sea with debris. The rocket’s cargo included a photon pair generator (Inset), which somehow survived intact. A similar device was later used to test new satellite technology that could help connect a global quantum Internet. Main image courtesy of NASA/Joel Kowsky; Inset courtesy of GomSpace.
