The Summer Challenge, a summer school of particle and nuclear physics for undergraduates, was held at the High Energy Accelerator Research Organization (KEK) on August 19th - 27th, 2025. This school is primarily intended for third-year undergraduate students and offers an opportunity to experience cutting-edge fundamental science and technology through lectures by leading researchers, visits to accelerator facilities, and hands-on research projects in particle and nuclear experiments.
Four staff members and six graduate students from N-Lab organized a quantum interference experiment ( link (Japanese) ). Six undergraduate students participated in this exercise, constructing their own experimental setup and readout system to perform measurements. They addressed challenges encountered during the experiment through discussion, creativity, and trial-and-error, ultimately succeeding in observing single-photon interference.
Undergraduates engaged in the experiment.
