标题： A Non-Oracle Quantum Search Algorithm and Its Experimental Implementation

摘要： Grover算法已经取得了巨大成功。 但量子搜索算法由于Grover的Oracle仍然不是完整的算法。 我们关注这个问题，并在绝热模型中提出了一种不需要Oracle的新量子搜索算法。 我们分析了量子搜索算法中的普遍困难，并展示了如何在当前算法中解决这些问题。 同时，该算法无需修改即可处理单解和多解搜索。 我们还在NMR量子计算机上实现了该算法。 这是首次进行真正的量子数据库搜索而非标记状态搜索的实验。 显示英文摘要

摘要： Grover's algorithm has achieved great success. But quantum search algorithms still are not complete algorithms because of Grover's Oracle. We concerned on this problem and present a new quantum search algorithm in adiabatic model without Oracle. We analyze the general difficulties in quantum search algorithms and show how to solve them in the present algorithm. As well this algorithm could deal with both single-solution and multi-solution searches without modification. We also implement this algorithm on NMR quantum computer. It is the first experiment which perform a real quantum database search rather than a marked-state search.
