Quantum Optics Group

Prof. Fumihiro Kaneda, Department of Physics, Tohoku University

WELCOME!!

We conduct research in the field of quantum optics using photons.

Photons and their quantum entanglement will be fundamental resources of future quantum technologies!!

In reality, to see quantum phenomena of light, we are working with classical optics most of the time.
