Abstract

Research and curriculum development on quantum information science is a novel but technologically and socially significant challenge for physics education. While the debate is open on the core content, the approaches, and the strategies for addressing the need of effective instruction on the subject-matter, some indications have begun to emerge. Among them, the importance of an earlier start of education and of helping students develop not only a theoretical knowledge, but also high-level experimental skills including ideal design and conduction of experiments. Such skills are challenging to attain in existing traditional programs and may be considered inaccessible at introductory level because of the difficulties connected with qubit implementations. Here we present the design process, the structure, and a preliminary evaluation of a course for secondary school that is aimed to promote the building of a basic but integrated understanding of quantum information science, including experimental design and lab activities. The course was developed within the model of educational reconstruction, and embedded into a conceptual change framework in physics and computation. The encoding of polarization and which-path information of a photon is used to engage students in the development of a global model of logical encoding and processing, in ideal experimental design of gates and circuits, and in their implementation on the optical bench. Data show the effectiveness of the course in promoting student engagement in the modelling of gates in different encodings, in fostering an understanding of the computational role of physical setups, and a positive attitude and interest towards quantum computation and innovative teaching methods.

用光子偏振和路径编码向中学生教授量子信息科学
量子信息科学的研究和课程开发是物理教育面临的一项新颖但在技术和社会方面意义重大的挑战。尽管对该学科的核心内容、教学方法和有效教学策略仍有争议,但一些迹象已经开始显现。其中,提早开始教育和帮助学生不仅掌握理论知识,而且培养高水平的实验技能,包括理想的设计和进行实验的重要性已经显现出来。这些技能在现有的传统课程中很难达到,而且由于与量子比特实现相关的困难,可能会被认为在入门阶段无法达到。在此,我们介绍一门中学课程的设计过程、结构和初步评估,该课程旨在促进学生建立对量子信息科学的基本但综合的理解,包括实验设计和实验活动。该课程是在教育重建模式下开发的,并嵌入了物理和计算的概念变革框架。通过对光子的偏振和路径信息进行编码,让学生参与逻辑编码和处理全局模型的开发、门电路的理想实验设计以及在光学工作台上的实现。数据显示,该课程有效地促进了学生参与不同编码的门建模,培养了学生对物理设置的计算作用的理解,以及对量子计算和创新教学方法的积极态度和兴趣。
