12 Facts About Quantum teleportation

Quantum teleportation is a technique for transferring quantum information from a sender at one location to a receiver some distance away.

Understanding quantum teleportation requires a good grounding in finite-dimensional linear algebra, Hilbert spaces and projection matrixes.

Resources required for quantum teleportation are a communication channel capable of transmitting two classical bits, a means of generating an entangled Bell state of qubits and distributing to two different locations, performing a Bell measurement on one of the Bell state qubits, and manipulating the quantum state of the other qubit from the pair.

Work in 1998 verified the initial predictions, and the distance of Quantum teleportation was increased in August 2004 to 600 meters, using optical fiber.

Variant of Quantum teleportation called "open-destination" Quantum teleportation, with receivers located at multiple locations, was demonstrated in 2004 using five-photon entanglement.
