论文摘要
Atom-Optics踢转子可用于在离散的基础设置中准备特定的动量分布。我们以这种势头在此基础上实施连续的量子步行和量子搜索协议。特别是，我们提出了从沃克（Walker）演变后的最终动量分布中识别特定明显状态的方法。我们的方案以当前的实验可能性为指导，使其可以使用Bose-Einstein冷凝水实验实现的量子步行。
The atom-optics kicked rotor can be used to prepare specific momentum distributions on a discrete basis set. We implement a continuous-time quantum walk and a quantum search protocol in this momentum basis. In particular we propose ways to identify a specific marked state from the final momentum distribution after the walker's evolution. Our protocol is guided by current experimental possibilities making it accessible to experimentally implemented quantum walks with Bose-Einstein condensates.
