远程状态准备使人们能够基于远程节点之间的共享纠缠来创建和操纵量子态。在这里，我们通过实验演示了压缩光的远程制备和操纵。通过在Alice‘s站对连续可变纠缠态的一个模进行零差投影测量，在Bob’s站创建了一个压缩态。此外，通过改变Alice态的投影参数，对制备的压缩态进行了旋转和位移运算。我们还证明了远程制备的压缩态对损耗是健壮的，并且基于N模连续可变的Greenberger-Horne-Zeilinger类光场可以远程制备N-1个压缩态。我们的结果验证了基于纠缠的模型用于连续变量量子密钥分发的安全性分析，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 a 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 an 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.
