Summary of the project
This project aims to develop an integrated system of quantum computers and quantum communication to realize a large-scale distributed quantum computer with fault tolerance (Fig. 1). We develop quantum interfaces that connect superconducting quantum computer chips via fiber-optic quantum communication (Fig. 2). With quantum memory and optomechanical crystals as our core technologies, we conduct research and development from diamond growth and diamond nanofabrication to 3D implementation.

Milestone by year 2030
The hybrid quantum interface and large-capacity quantum memory enable network connectivity with quantum error correction (Fig. 1).

Milestone by year 2025
To show that the number of qubits can be expanded to the scale needed for quantum error correction, we will realize a connection between quantum computers via quantum communication using a hybrid quantum interface (Fig. 2).
