- New material platform for large-scale integration of superconducting qubits -

Researchers at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), in collaboration with researchers at the National Institute of Advanced Industrial Science and Technology (AIST, President: Dr. ISHIMURA Kazuhiko) and the Tokai National Higher Education and Research System Nagoya University (President: Dr. MATSUO Seiichi) have succeeded in developing an all-nitride superconducting qubit using epitaxial growth on a silicon substrate that does not use aluminum as the conductive material. This qubit uses niobium nitride (NbN) with a superconducting transition temperature of 16 K (-257 °C) as the electrode material, and aluminum nitride (AlN) for the insulating layer of the Josephson junction. It is a new type of qubit made of all-nitride materials grown epitaxially on a silicon substrate and free of any amorphous oxides, which are a major noise source. By realizing this new material qubit on a silicon substrate, long coherence times have been obtained: an energy relaxation time (T₁) of 16 microseconds and a phase relaxation time (T₂) of 22 microseconds as the mean values. This is about 32 times T₁ and about 44 times T₂ of nitride superconducting qubits grown on a conventional magnesium oxide substrate.

- 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.

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), Sumitomo Osaka Cement Co., Ltd. (President: MOROHASHI　Hirotsune), and Waseda University (President: TANAKA Aiji) jointly developed the first transparent fiber-millimeter-wave-fiber system in the 100-GHz band using a low-loss broadband optical modulator with direct photonic down-conversion. The developed broadband modulator and photonic down-conversion technology were utilized to successfully demonstrate a high-speed transmission of more than 70 Gbit/s over a wired and wireless converged system consisting of two optical fiber links and a 20 m radio link at 101 GHz.

An international team of researchers from Japan Aerospace Exploration Agency (JAXA), National Aeronautics and Space Administration (NASA), Boston University, University of Leicester, Space Research Corporation, and the National Institute of Information and Communications Technology (NICT), led by Dr. James O’Donoghue, found that Jupiter’s intense aurora, the most powerful in the solar system, is responsible for heating the entire planet’s upper atmosphere to surprisingly high temperatures.

– Toward efficient utilization of a new radio-communications resource between microwave and infrared light –

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has developed a broadband and high-precision terahertz (THz) frequency counter based on a semiconductor-superlattice harmonic mixer. It showed a measurement uncertainty of less than 1 x 10-16 from 0.12 THz to 2.8 THz. This compact and easy-to-handle THz counter operating at room temperature suits for various THz applications supported by the next-generation ICT infrastructure, “Beyond 5G / 6G”.

- >120 nm signal bandwidth comprising 552 WDM channels and using both-doped fiber and Raman amplification -

Researchers from the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), Network Research Institute, succeeded the first S, C and L-bands transmission over long-haul distances in a 4-core optical fiber with standard outer diameter (0.125 mm). The researchers, lead by Benjamin J. Puttnam, constructed a transmission system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies, to achieve a transmission demonstration with date-rate of 319 terabits per second, over a distance of 3,001 km. Using a common comparison metric of optical fiber transmission the data-rate and distance produce of 957 petabits per second x km, is a world record for optical fibers with standard outer diameter.

Keeping a daily gratitude journal for as little as two weeks can help keep students motivated for months

Our dynamically changing lifestyle can make it hard for many to stay motivated on work and study, which calls for new intervention strategies. In a recent study published in BMC Psychology, researchers explore how nurturing feelings of gratitude can enhance motivation among college students. Their results show that a keeping a daily gratitude journal for only two weeks has a positive impact on academic motivations that can last months.

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has released white papers on “Beyond 5G/6G” and “Quantum Network” to accelerate R&D collaboration with other research institutions.
