# Quantum Teleportation Reaches Farthest Distance

- Quantum teleportation doesn't mean it's possible for a person to instantly pop from New York to London, but they can instantly transport information through quantum teleportation. This works thanks to a bizarre quantum mechanics property called entanglement.
- 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.
- 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.
