From ‘Ultimate Nano Material Synthesis’ to
‘Quantum Electronics Development’
A society that widely utilizes devices leveraging quantum effects, such as quantum computers and artificial intelligence (AI) semiconductors, is approaching.
The development of quantum materials specialized for such quantum electronics is a very important social issue.
We focus on atomic-layer materials like carbon nanotubes, graphene and transition metal dichalcogenides, which are expected to play a significant role in quantum electronics, and we are working on developing technologies for their high-quality synthesis and functionalization.
Furthermore, we aim to create innovative quantum devices using these materials and implement them in society.
