论文摘要
远程状态准备使人们能够根据遥远节点之间的共同纠缠创建和操纵量子状态。在这里，我们在实验上证明了偏远的准备和操纵挤压光。通过在爱丽丝车站的连续变量纠缠状态的一种模式下执行同性恋射击测量，在鲍勃车站创建了挤压状态。此外，通过更改爱丽丝状态的投影参数，将旋转和位移操作应用于准备的挤压状态。我们还表明，远程准备的挤压状态对于损失具有强大的稳定性，并且可以根据N模式连续可变的Greenberger-Horne-Horne-Horne-Zeilinger样状态来远程制备N-1挤压状态。我们的结果验证了与连续变量的量子密钥分布的安全分析中使用的基于纠缠的模型，并在远程量子信息处理中具有潜在的应用。
Remote state preparation enables one to create and manipulate a quantum state based on the shared entanglement between distant nodes. Here, we experimentally demonstrate remote preparation and manipulation of squeezed light. By performing homodyne projective measurement on one mode of the continuous variable entangled state at Alice's station, a squeezed state is created at Bob's station. Moreover, rotation and displacement operations are applied on the prepared squeezed state by changing the projective parameters on Alice's state. We also show that the remotely prepared squeezed state is robust against loss and N-1 squeezed states can be remotely prepared based on a N-mode continuous variable Greenberger-Horne-Zeilinger-like state. Our results verify the entanglement-based model used in security analysis of quantum key distribution with continuous variables and have potential application in remote quantum information processing.
