To realize highly secure communication required for sensitive personal information, quantum key distribution (QKD) was applied to a video conference system for clinical use in a field trial. We demonstrated that the system provides a QKD secured environment for discussion and for sharing screens of patient cases among medical experts. The results indicated that our QKD system’s secure key rate is sufficient for a video conference in real time. This demonstrated that QKD is applicable to video conference systems for practical use.

We developed a system for real-time transmission of genome sequence data using quantum cryptography and have succeeded in the quantum cryptography transmission of genome sequence data with data volumes exceeding several hundred gigabytes. This demonstrated that quantum cryptography can transmit large amounts of data and has practical applications in the fields of genomic research and genomic medicine.
