Photons teleported 100 kilometers in new quantum teleportation record

The Breakthrough

The team was able to send and receive quantum information over 62 miles of fiber. The team was able to achieve this using single-photon detectors cooled to one degree above absolute zero. Although only 1 percent of photos make it all the way through all the way, the new molybendum silicide detectors were significantly better at detecting weak signals.

The Implications

Quantum computing not only could be the start of a new era of computing, but the researchers behind this project also believes that this fiber-optic specific finding could be applied to a “quantum internet” that can send messages security. Previously, quantum teleportation was achieved over a span of 144 kilometers, but that passed the information through the open air. Fiber optics is far more feasible for quantum teleportation applications.
