Toshiba, ToMMo, Tohoku University Hospital, and NICT Demonstrate the Use of Quantum Cryptography Communication and Secret Sharing Technologies for Distributed Storage of Genome Analysis Data

-Contributing to safe data management in the fields of genomic research and medicine-

Toshiba Corporation, Tohoku University Tohoku Medical Megabank Organization (ToMMo), Tohoku University Hospital, and the National Institute of Information and Communications Technology (NICT) have developed a distributed storage technology that combines quantum cryptography communication and secret sharing technologies, successfully demonstrating the world’s first experimental large-scale1 genome analysis data backup to multiple sites2. These technologies will allow data backup that prevents data leaks and tampering over long periods and are expected to contribute to safe data management in the fields of genomic research and medicine.
A part of this work was performed for Council for Science, Technology and Innovation (CSTI), Cross-ministerial Strategic Innovation Promotion Program (SIP), “Photonics and Quantum Technology for Society 5.0” (Funding agency: QST). Toshiba, ToMMo, Tohoku University Hospital, and NICT will present the details of these technologies and their experimental demonstration at the 11th International Conference on Quantum Cryptography (QCrypt 2021). ・・・read more

Memory Neurobiology Project

Neural Correlate of Pavlovian Conditioning

-Hijacking the command neuron governs Pavlovian conditioning-

The group lead by Executive Researcher, YOSHIHARA Motojiro, and Senior Researcher, SAKURAI Akira, at the National Institute of Information and Communications Technology, Kobe (NICT, President: TOKUDA Hideyuki, Ph.D.) unraveled a neural correlate of Pavlovian conditioning. The feeding command neuron, which was discovered by the same group in the brain of fruit flies (Nature, 2013)1, was found to be hijacked by an originally-independent stimulus, leading to the conditioned response. Furthermore, the experimental system of Pavlovian conditioning made possible real-time observation of cell-cell connection for memory formation.
These results were published in Current Biology at 11 AM on August 4 (US Eastern Standard Time) in 2021. ・・・read more

Frontier Research laboratory Superconductive Device Project


Development of High-sensitivity, Wide-IF Band Heterodyne Receiver in Terahertz Frequency Range

-Realized by NICT's original superconducting device structure using magnetic materials-

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has developed a unique superconducting hot electron bolometer mixer (HEBM) using magnetic materials. As a result, the noise of the 2 THz band heterodyne receiver has been reduced and the wide IF band has been achieved. The 2 THz band HEBM produced this time has a low noise performance of about 570 K (DSB), which is about 6 times the quantum noise limit, and a wide IF band characteristic of about 6.9 GHz, which is about 3 GHz larger than the conventional structure HEBM. Both of these are world-class performance.・・・read more
