Self-introduction
I specialize in experimental research on fundamental physics using quantum electronics technology, focusing on experimental research on foundation of quantum mechanics using quantum manipulation of photons. Quantum mechanics supports industries and lifestyles around us and has become the basic of quantum information science in recent years. But nobody understands its fundamentals and controversy is still ongoing. It was noticed by the 2022 Nobel Prize in Physics, which further deepened the mystery. I am continuing my research with the aim of elucidating the basics of quantum mechanics.
