An Experience Report on Teaching Quantum Key Distribution to Incoming College Freshmen

Quantum information science and engineering (QISE) is rapidly emerging as a critical field, requiring scientists and engineers with specialized knowledge in quantum technologies.To help address this need, we organized a three-week summer workshop for incoming college freshmen, introducing them to foundational topics in calculus, physics, and programming.Within the physics portion of the program, students explored quantum mechanics and worked specifically on understanding the BB84 quantum key distribution (QKD) protocol.This manuscript focuses on our experience teaching the BB84 QKD protocol, describing what worked well, the challenges we faced, and the lessons we learned.We share successes, obstacles, and strategies for future iterations to improve educational outcomes related to this critical aspect of quantum science.
