摘要:

近年来,随着光力学的发展,固体中涉及数万亿原子集体运动的振动逐渐进入量子控制的领域。基于近年来在金刚石运动态的光学控制方面取得的显著进展,本文报道了在环境条件下从光束到宏观金刚石振动态的量子隐形传态的实验演示。通过量子过程层析成像,我们证明了平均隐形传态保真度(90.6+/- 1.0)%,明显超过了2/3的经典极限。该实验将量子隐形传态的目标推向了迄今为止最大的目标,对光机械量子控制和量子信息科学具有有趣的意义。

英文摘要:

With the recent development of optomechanics, the vibration in solids, involving collective motion of trillions of atoms, gradually enters into the realm of quantum control. Built on the recent remarkable progress in optical control of motional states of diamonds, here we report an experimental demonstration of quantum teleportation from light beams to vibrational states of a macroscopic diamond under ambient conditions. Through quantum process tomography, we demonstrate average teleportation fidelity (90.6+/- 1.0)%, clearly exceeding the classical limit of 2/3. The experiment pushes the target of quantum teleportation to the biggest object so far, with interesting implications for optomechanical quantum control and quantum information science.
