Researchers from China successfully teleported a photon from Earth to a satellite 500 km away. The work is an essential step towards establishing a global-scale quantum internet.
Not long ago, in the early 1990s, scientists only speculated that teleportation using quantum physics could be possible. Since then, the process has become a standard operation in quantum optics labs around the world. In fact, just last year, two separate teams conducted the world’s first quantum teleportation outside of a laboratory.
