Applied Quantum 
Technology

Our group focuses on these quantum functionalities of diamond, specializing in the research and development of next-generation quantum computers and high-precision sensors. Our core strength lies in our proprietary expertise in precisely creating and controlling qubits within diamond wafers, as well as developing optical and electrical methods for the highly efficient readout and manipulation of quantum information.

Specific Research Themes
We are focused on the integration of qubits and the extension of coherence time (the duration quantum information is preserved), both of which are fundamental to quantum computing. This mission involves establishing highly advanced technologies, such as diamond surface treatments to stabilize device operation and the design of nanostructures to control qubit-qubit interactions.

In the field of Quantum Sensing, we are developing devices capable of detecting minute magnetic fields and temperature fluctuations with extreme sensitivity. We are currently conducting proof-of-concept demonstrations for applications in medical fields (biomagnetic imaging) and advanced material analysis.

Vision: The Diamond Quantum Internet
We have also proposed a highly ambitious concept: the realization of a Quantum Internet via Diamond Networks. By leveraging state-of-the-art diamond processing, we aim to create on-chip diamond room-temperature quantum processors and establish technologies to transfer quantum information to remote locations via photonic paths. This will pave the way for a quantum communication network that integrates geographically dispersed quantum devices.

Positioning synthetic diamond as the "ultimate platform" for quantum technology, we conduct integrated research—from fundamental physics to the prototyping of applied devices—to drive the future of information and measurement technology.
