The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), NTT Corporation (NTT, President: Mr. SHIMADA Akira), Tohoku University (President: Dr. TOMINAGA Teiji) and the Tokai National Higher Education and Research System Nagoya University (President: Dr. SUGIYAMA Naoshi) succeeded in developing a new type of superconducting flux qubit that operates in zero magnetic field.

Facilitating a smooth transition to post-quantum cryptography to ensure the safety and security of social infrastructure

Tokyo - October 7, 2024 - TOPPAN Digital Inc. (TOPPAN Digital), a TOPPAN Group company and wholly owned subsidiary of TOPPAN Holdings Inc. (TYO: 7911), the National Institute of Information and Communications Technology (NICT), and ISARA Corporation (ISARA) have developed SecureBridge™, a smart card system capable of supporting both currently used public-key cryptography and post-quantum cryptography (PQC) that is secure against attacks from quantum computers.

- A simple, wide-band optical communication system realized with optical comb and frequency reference distribution -

An international research team led by the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) demonstrated a coherent optical fiber communication system with a total transmission capacity of 336 Tb/s. The system uses a single light source combined with optical comb generation and frequency reference distribution, eliminating the need for hundreds of built-in light sources within transponder modules.

TOKYO—September 3, 2024—NTT Corporation (Headquarters: Chiyoda Ward, Tokyo; Representative Member of the Board and President: SHIMADA Akira; hereinafter "NTT") and Cybersecurity Laboratory of the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) conducted a systematic review of papers published as user studies (studies involving participants) in the security and privacy field. The review quantitatively revealed that many existing studies focus on populations from limited geographical and cultural regions, primarily in the West.

The Universal Communication Research Institute of the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has successfully developed a 21-language, fast and high-fidelity neural text-to-speech technology. The development of this technology has made it possible to synthesize one second of speech at high speed in just 0.1 seconds using a single CPU core, which is about eight times faster than the conventional methods. This technology also enables fast synthesis with a latency of 0.5 seconds on a mid-range smartphone without network connection.

Our brain learns and remembers actions differently based on the level of decision uncertainty

A study published online in the journal Nature Human Behaviour challenges the belief that identical physical actions are governed by the same motor memory, regardless of the decision-making process involved. Researchers from the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) and HONDA R&D Co., Ltd. have discovered that the brain differentiates and stores motor memories based on the level of uncertainty experienced during decision-making.

– NICT promotes global partnerships in AI –

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) today established the GPAI Tokyo Expert Support Center as the third GPAI Expert Support Center in the world following those in Paris and Montreal. The Japanese government proposed the establishment of an organization in Tokyo that supports AI experts affiliated with GPAI, and it was approved at the GPAI Ministerial Council in December 2023.

- World's first measurement of vertical cloud motion from space -

The Japan Aerospace Exploration Agency (JAXA, President: Hiroshi Yamakawa) and the National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda) have released the first images from the Cloud Profiling Radar (CPR) on board Earth Cloud Aerosol and Radiation Explorer (EarthCARE) (Japanese nickname: Hakuryu ), which was jointly developed with the European Space Agency (ESA), and launched at 7:20 a.m. (JST) on May 29, 2024. The CPR is the world’s first spaceborne Doppler radar in the W-band (94 GHz) and was jointly developed by JAXA and NICT.

- Achieved with novel technologies to open new wavelength regions for future optical communication infrastructure -

An international joint research team led by the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), demonstrated a record-breaking aggregate optical transmission bandwidth of 37.6 THz to enable a new data-rate record of 402 terabits per second in a commercially available standard optical fiber.

— Major Step Toward Realization of 5G Communication from Stratosphere —

TOKYO, JAPAN, May 28, 2024— SKY Perfect JSAT Corporation, NTT DOCOMO, INC., the National Institute of Information and Communications Technology (NICT) ,and Panasonic Holdings Corporation (Panasonic HD) jointly announced today that they have successfully conducted a 5G communication verification test in the 38GHz band from an altitude of approximately 4km using a small Cessna aircraft operated by Kyoritsu Air Survey Co., Ltd. simulating the eventual use of High-Altitude Platform Stations (HAPS) . The demonstration was the first of its kind in the world.
