Thermal entanglement and teleportation in a dipolar interacting system

Quantum teleportation, which depends on entangled states, is a fascinating subject and an important branch of quantum information processing. The present work reports the use of a dipolar spin thermal system as a quantum channel to perform quantum teleportation. Non-locality, tested by violation of Bell’s inequality and thermal entanglement, measured by negativity, unquestionably show that even entangled states that do not violate Bell’s inequality can be useful for teleportation.
