Trans-Scale Quantum Science Institute was established as a crosscutting research platform for quantum science including cosmology, particle physics, condenced matter physics, quantum information and mathmatics. Our research objectives are to create new concepts & fields that penetrate the hierarchy of physics ranging from cosmology to solid-state physics centering on quantum mechanics, and thereby creating future quantum technologies.

Background

Quantum theory in high energy physics is now bringing about a revolution to condensed matter physics by introducing new concepts and technologies. For example, topological gauge-field theories proposed in high energy physics are now recognized as models for topological phases in matter such as quantum Hall systems, and are drawing attention as a promising platform for fault tolerant quantum computation and quantum memory. In addition, Weyl fermion, which had been introduced as a model of neutrino, was discovered in solid-state materials recently and that is now leading to a development of novel high-speed memory. While looking ahead to the future society where those quantum technologies are developed further and quantum computers, quantum communication, and quantum devices are commonly used, our institute was established in the aim of pursuing crosscutting collaborative research among cosmology, particle physics, condenced matter physics, quantum information and mathmatics, and conducting basic development of quantum technology that applies the result of basic research instantaneously.

Activities

1. Crosscutting and Pan-hierarchical Research Area

In order to conduct crosscutting research on various levels of physics from cosmology and particle physics to condensed matter physics, we assemble four research environments of the University of Tokyo that are Graduate School of Science, IPMU, the Institute for Solid State Physics, and Cryogenic Research Center, and we align and set four research areas: creation of basic material cosmology, creation of quantum materials, creation of quantum information technology, and creation of quantum advanced measuring technologies. Moreover, we have placed a task force consisting of faculty members and researchers from partner departments and set strategic themes for crosscutting and multifaceted research led by chief scientists comprised of assistant professors level personnel.


2. Building International Research Platform

For crosscutting and advanced research results, we are aiming to build an international research platform in which research groups with different technologies tie networks each other and faculty members, young researchers, and graduate students are able to lever research resources strategically among departments and labs from home and abroad. Therefore, we plan to mobilize human resources by inviting faculty members from international partner research hubs, accepting foreign young researchers openly, and so forth. In order to facilitate them strategically, we established International Strategy Office led by university research administrators for international agreements and personnel exchanges.


3. Development of "Quantum Natives"

In the face of the future society where quantum technologies such as quantum information are widely used, we are aiming to train young talents who have a good command of quantum technologies and are even able to build the technologies on their own. Therefore, we send young talents to international partner research hubs, support their creative research projects, and build a support system by companies for doctors.
