Japan is making significant strides in quantum communications, focusing on building practical, real-world infrastructure rather than solely on quantum computing. A new 600-kilometer quantum-encrypted network is under development by Toshiba, NEC, and NTT Docomo Business, connecting Tokyo, Nagoya, and Osaka. This initiative aims to demonstrate quantum key distribution (QKD) for high-security applications in sectors like healthcare and finance, with broader social implementation targeted around 2030. This pragmatic approach integrates quantum security technologies into existing networks, contrasting with some other nations' focus on connecting quantum processors or large-scale satellite-terrestrial systems.
