Vision for the future

Networking of quantum communications

Realization of ultra-long-range quantum communications

By introducing the technology of Quantum security field into drones and satellites, it is possible to realize a large-capacity and secure network that covers the earth. Now, available radio frequencies in mobile communications networks are being tightly regulated, but laser light is not yet subject to the regulation. In addition, the laser beam used in quantum communication has advantages over radio waves, such as increased power efficiency and reduced interference, because it is broadband and highly directional. In space, it is expected that communications of quantum cryptography on a global scale will become possible because of almost no attenuation of light as opposed to optical fiber lines on the ground.


Realization of quantum networks

A quantum network realized by integrating long-distance quantum communications with quantum technologies is envisioned. It is expected that various technologies such as the following will be realized by communicating quantum information over the network.

Long-distance quantum cryptography

Long distance quantum cryptography by relaying quantum information without destroying the information

Quantum network of optical clocks

Quantum network of optical clocks for recording accurate time by connecting separate optical clocks to each other

Distributed quantum computing

Distributed quantum computer having high computing power by interconnection of small and medium scale quantum computers

Secret quantum computation

Secret quantum computation that can be performed by a distributed quantum computer without third party knowing its contents

Construction of Quantum technology platform

Ultimately, we aim to build Quantum technology platform by (1) pioneering a quantum security fusion area where security technology of quantum cryptography and network technology are fused, (2) broadening quantum communications by collaborating with the satellite communications field, (3) fusing quantum computing and quantum measurement and sensing , and (4) integrating with current networks such as the Internet.
