量子纠缠科研平台反哺实验教学的探索

Research on Feedback Experiment Teaching of Quantum Entanglement Research Platform

量子纠缠是量子信息处理中一种重要的物理资源,其广泛应用于量子通信、量子计算、量子精密测量等领域。本文介绍了一种基于线性光学系统的量子纠缠科研平台,该平台可以实现双光子偏振纠缠态的制备、操控和测量。作者在开展科研活动的同时,秉持科研反哺实验教学的理念,对科研实验做了教学化设计和改造,开发了两项适用于本科教学的实验项目:量子纠缠态制备和纠缠特性测量。这是提升课程高阶性、培养学生创新实践能力的有效探索和尝试。

Quantum entanglement is an important physical resource in quantum information processing,which is widely used in quantum communication,quantum computation,quantum precise measurement and other fields.This paper introduces a quantum entanglement research platform based on linear optical system,which can realize the preparation,control and measurement of two-photon polarization entangled states.At the same time of carrying out scientific research activities,the authors adhere to the idea that the scientific research platform feeds back the experimental teaching.They design and reform the scientific research experiment teaching,and develop two teaching experiments for college students.One is the preparation of quantum entangled states and another is the detection of entanglement properties.It is an effective exploration and attempt to improve the high-level attribute of the curriculum and cultivate students’innovative and practical ability.
