Self-introduction
I specialize in the foundations of quantum mechanics, quantum measurement theory, and quantum information theory. To observe natural phenomena, capture the essence of physical laws, model them mathematically, and ultimately understand and control nature, a solid understanding of measurement theory is essential. With this in mind, my research focuses on using quantum measurement theory to explore the fundamental limits of observation and how those limits can be physically realized.
I’m also deeply interested in the rapidly developing field of quantum technologies. In particular, I study the mathematical structures within quantum mechanics that underpin these technologies, as well as the origins of quantum behavior that give quantum information processing an edge over classical approaches.
More recently, I’ve been involved in interdisciplinary research that connects the foundations of quantum mechanics with fields like cognitive science, biology, and medical science—especially through experimental studies using quantum computers and applications of quantum algorithms.
At RIKEN, I hope to collaborate with researchers from diverse backgrounds and contribute to society through scientific discoveries born from these collaborations.
