研究方向:量子算法,量子计算与量子信息理论。
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。量子计算把待求解问题映射到量子体系中,利用量子力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:量子态的制备;量子开放体系动力学的量子模拟;求解薛定谔方程、本征值问题、离散数学问题、数据拟合问题、优化问题等。
