Quantum information has already been transferred dozens of miles, but this is the farthest it's been transported using an optical fiber, and then recorded and stored at the other end. Other quantum teleportation experiments that beamed photons farther used lasers instead of optical fibers to send the information. But unlike the laser method, the optical-fiber method could eventually be used to develop technology like quantum computers that are capable of extremely fast computing, or quantum cryptography that could make secure communication possible.
Physicists think quantum teleportation will lead to secure wireless communication - something that is extremely difficult but important in an increasingly digital world. Advances in quantum teleportation could also help make online banking more secure.
The research was published Sept. 21 in the journal Nature Photonics.
