- FY2026AdvancedAnnual report
「In January 2026, we successfully demonstrated Japan's first terabit-class large-capacity data transmission over a commercial network connecting the Osaka-Sakai Data Center with central Osaka, combining two post-quantum security technologies: quantum key distribution (Note 11) and post-quantum cryptography (Note 12). Through multilayer defense at the physical and application layers (Note 13), we transmitted 57.6Tbps of large-capacity data without increasing latency.」
