TL;DR
This paper investigates the use of a dipolar spin thermal system as a quantum channel for teleportation, demonstrating that entangled states useful for teleportation can exist even without violating Bell's inequality.
Contribution
It introduces a novel application of dipolar spin thermal systems as quantum channels and explores their entanglement and non-locality properties for teleportation.
Findings
Entangled states can be useful for teleportation without violating Bell's inequality.
Thermal entanglement measured by negativity indicates potential for quantum communication.
Non-locality assessed through Bell's inequality violation supports teleportation capability.
Abstract
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.
