标题： Contribution of classical correlation and entanglement in the non-classical teleportation fidelity

摘要： 众所周知，纠缠是量子隐形传态的资源。 使用经典关联（CC），隐形传态可以在一定程度上实现，其隐形传态保真度（TF）可达$2/3$。 在本工作中，我们研究了退相干存在下TF、纠缠和CC的关系。 我们发现，相对于退相干强度，显著增加的经典关联可以将隐形传态保真度带入非经典区域，而此时纠缠却在减少。 我们还研究了利用弱测量和反向弱测量（WMRWM）技术保护TF和纠缠。 在这里我们发现，最大化纠缠保护并不一定能优化TF和CC。而TF的最大化则表明CC也达到了最大化。 因此，共享态的纠缠和经典关联以一种复杂的方式参与了隐形传态，这需要在未来进一步探索。 显示英文摘要

摘要： It is well known that entanglement is the resource of quantum teleportation. Teleportation can be accomplished using classical correlation (CC) with a teleportation fidelity (TF) upto $2/3$. In the present work we have studied TF, entanglement and CC in the presence of decoherence. We have found that significant increment of CC with respect to the strength of decoherence can lead TF in the non-classical region while entanglement is decreasing. We have also studied the protection of TF and entanglement using the technique of weak measurement and reverse weak measurement (WMRWM). Here we found that maximum protection of entanglement does not optimize the TF and CC. While optimization of TF indicates maximization of CC. Therefore, both entanglement and classical correlation of the shared state take part in the teleportation in a complex manner that needs to be explored in the future.
