题目: Decomposition of unitary gates

报告人: 李志光(Chi-Kwong Li) 教授, 美国威廉玛丽学院

摘要: In quantum information science, quantum gates acting on vector states are unitary transformations. It is descirable from the theoretical as well as practical point of view to decompose a general unitary transformation into simple ones that are easy to control and implement. In this talk, we will describe current research on this topic.
