摘要：

It is experimentally demonstrated that entangled quantum states can be used to amplify perturbations and to increase changes in observable values. The physical system is seven nuclear spins of single-labeled C-13-benzene in a liquid crystalline matrix. An entangled state of six proton spins was used to monitor interaction with the C-13 spin.
