团队简介

量子信息与信号处理实验室主要由金瑶（教授），周苏（副教授）两位成员组成。团队研究方向：

1.量子信息：本实验室利用由环境系统关联诱导的系统之间的间接关联来调控系统演化，进而提高测量精度及传态保真度。另一方面，研究使环境最大参数化的测量基的选择问题，进而建立基于环境态的信息存储机制，并将其应用于量子度量和量子传态过程中。尝试利用环境对系统初始态的记忆，以环境为媒介，实现态参数的多次测量，进而使量子态的保存时间及传态的保真时间得到大幅度的增加。

2.数字信号处理：近地空间的大气层处于电离的等离子体状态，本实验室利用计算机编程语言Python分析DMSP等卫星观测数据，研究等离子体中的波动、带电粒子投掷角分布、粒子沉降与激发的极光现象，探索极区粒子沉降的物理机制。
