Scientists at the National Institute of Standards and Technology (NIST) have conducted an experiment confirming that quantum communication over long distances is possible. Research team has successfully "teleported" quantum information carried in light particles over 100 km (62 miles) of optical fiber, breaking a previous record by four times.
The term quantum teleportation involves the transfer, or remote reconstruction, of information encoded in quantum states of matter or light. Teleportation has the potential of offering new possibilities such as unbreakable encryption and advanced code-breaking techniques.
The basic method for quantum teleportation was first proposed over 20 years ago. Different research groups have been successful in teleporting quantum information over even longer distances, however, these experiments have been conducted in free space, while the ability to perform teleportation over conventional optical fiber is far more flexible solution for network designs.
