研究领域
我们的主要研究方向是量子算法与量子仿真，量子机器学习和基于忆阻器网络的计算。


随着电子线路的尺寸越来越小，量子效应开始显现，如何在这种情况下进行计算？在经典计算机上模拟量子体系的复杂度随体系的大小呈指数增长，如何高效的模拟量子体系？量子计算机是由量子体系构建而成，量子信息的存储，传输，处理和读出都必须服从量子力学原理。量子计算把待解决的问题映射到一个特定的量子体系中，利用物理学原理求解这些问题。我们研究的核心问题是：哪些问题在经典计算机上难以求解，而在量子计算机上可以高效解决？设计高效的量子算法解决这些问题。
我们已经发展了一些量子算法：求解一个物理体系的薛定谔方程；制备一个物理体系的任意一个量子态；量子体系动力学的仿真；确定 Ramsey 数；绝热量子算法求解EC3 问题；求解本征值问题，搜索问题，离散数学问题，奇异值分解问题，线性方程组，数据拟合问题，优化问题等。已在国际重要期刊发表文章10余篇。主持国家自然科学基金面上项目一项，陕西省自然科学基金面上项目一项。
