Japan uses quantum confidential communication technology to transmit large amounts of genomic data

Japan’s Toshiba Corporation and Tohoku University of Japan issued a joint communique on the 14th, said its researchers used quantum confidential communication technology in a short period of time to transmit up to hundreds of gigabytes of human genome sequencing data, said to be the world’s first quantum confidential communication technology such a short time to transmit large amounts of data. Quantum confidential communication technology can use quantum technology to encrypt the transmission of information, it has the characteristics of good confidentiality, but it has not solved the problem of the amount of data transmitted for a long time.

Japan uses quantum confidential communication technology to transmit large amounts of genomic data

Researchers at the two agencies have developed a quantum confidential communication technology that can be used to transmit large amounts of data, the communique said. From July to August 2019, researchers conducted experiments between two facilities in Sendai, Japan, about 7 kilometers apart, using dedicated fiber optic lines.

The data from the sequencing of the human genome was transmitted in the experiment. A total of 24 people’s genomic data was transmitted in two batches, and each batch of 12 people’s genomic data was successfully transmitted in less than 2 minutes after sequencing. According to the introduction, the total amount of data transferred reached hundreds of gigabytes.

The paper says the experiment shows that quantum confidential communication technologies can be used to transmit large amounts of data, and that the results are expected to be used in areas such as genomics research and medicine.
