NEC Corporation (NEC), the National Institute of Information and Communications Technology (NICT), Kyoto University, and Keio University have succeeded in the processing, highly confidential transmission, and distributed storage of optimized design information for the smart manufacturing field. This was achieved in a verification test applying a quantum secure cloud system that integrates quantum cryptography and secret sharing technologies.
This verification test confirmed for the first time that advanced design information for next-generation lasers (photonic crystal lasers), optimized by a next-generation accelerator that utilizes quantum computing technology, can be securely transmitted between remote sites using an internet connection.
The success of this verification test demonstrates the applicability of the quantum secure cloud system in deriving optimal design parameters—critical design information for photonic crystal lasers, which are expected to become the core of future smart manufacturing—via quantum computation. Future applications are anticipated in various manufacturing sectors, including the semiconductor and automotive industries.
This verification test was conducted as part of the Cross-ministerial Strategic Innovation Promotion Program (SIP) theme, "Photonics and Quantum Technology for Society 5.0," led by the Cabinet Office, Government of Japan, and managed by the National Institutes for Quantum Science and Technology (QST).
