Quantum Teleportation

Quantum Teleportation (量子テレポーテーション Ryoushi Tereptshon) is the instantaneous transference of properties of quantum information, physical information moved to the state of a quantum system, from one system to another without physical contact. The application of this term in Digimon Tamers refers to the interchangeabliity between realized and metaphorized states in the Digital World and Real World respectively.

Quantum teleportation plays a very crucial role throughout the duration of Digimon Tamers, particularly during the emergance of the D-Reaper in Shinjuku, when Zero-Arms: Grani was transported there to aid Dukemon from being completed in the Digital World's plane. In DT48, Shibumi explains this in detail (under construction)
