About the Jointly-hosted Workshop

One of the deepest questions in science today is the relationship between gravity and quantum mechanics. Albert Einstein spent much of the latter part of his life tackling this question, and research into this question has led to many beautiful mathematics and scientific discoveries such as string theory, M-theory etc. However, recently, researchers have begun to ask if there are "table-top" experiments which can probe this question - experiments, though still very challenging, that may be able to unlock some answers to these deep issues. This new line of inquiry is opening up new fields of research and brings together theorists and experimentalists to investigate what types of "table-top" experiments can shed light on the enigmatic relationship between gravity and quantum. Solving this - and uncovering the fundamental relationship between gravity and quantum mechanics would be a ground breaking result - impacting many fields of science. This workshop - held in Tokyo - will provide an introduction to this new area of research, and bring together researchers wishing to learn and those already working, in this exciting new field of research. See a quick video intro here.

 

The workshop, jointly run by OIST and Univ of Tokyo, will run for two days from December 14 - 15 2026 at the Okinawa Institute of Science and Technology offices in Toranomon Hills, Minato City, Tokyo. 

The workshop will feature pedagogical lectures and talks by the following invited speakers.

  • Prof. Julen Pedernales (Delft University of Technology)
  • Prof. Marko Toroš (University of Ljubljana)
  • Prof. Sugumi Kanno (Kyushu University) (To be confirmed)
  • Prof. Tomohiro Fujita (Ochanomizu University)
  • Prof. Haruna Katayama (Hiroshima University)
  • Prof. Akira Matsumara (Kyushu University)
  • Prof. Yasusada Nambu (Nagoya University) (To be confirmed)
  • Prof. Kazuhiro Yamamoto (Kyushu University) 

In addition, the following research groups from the University of Tokyo will host laboratory tours

  • Prof. Yuta Michimura (Instrument science and astronomy of gravitational waves. Laser interferometry)
  • Prof. Masaki Ando (Observation of gravitational waves. Tests of GR and macroscopic quantum measurement)
  • Prof. Kiyotaka Aikawa (Levitated Optomechanics. Hybrid Quantum Systems)

In parallel, we will have a poster session.
