Riken is a large scientific research institute in Japan. Founded in 1917, it now has about 3,000 scientists on seven campuses across Japan, including the main site at Wakō, Saitama Prefecture, just outside Tokyo. Riken is a Designated National Research and Development Institute, and was formerly an Independent Administrative Institution. "Riken" is a contraction of the formal name Rikagaku Kenkyūjo, and its full name in Japanese is Kokuritsu Kenkyū Kaihatsu Hōjin Rikagaku Kenkyūsho and in English is the Institute of Physical and Chemical Research. Riken conducts research in many areas of science, including physics, chemistry, biology, genomics, medical science, engineering, high-performance computing and computational science, and ranging from basic research to practical applications with 485 partners worldwide. It is almost entirely funded by the Japanese government, and its annual budget is about ¥88 billion (US$790 million).

Quantum entanglement of three spin qubits demonstrated in silicon

“An all-RIKEN team has increased the number of silicon-based spin qubits that can be entangled from two to three, highlighting the potential of spin qubits for realizing multi-qubit quantum algorithms1. Quantum computers have the potential to leave conventional computers …

Electron–electron and spin–orbit interactions compete to control the electron

“The interactions that compete to control electron spin can give rise to novel electronic states useful for future quantum technologies In a finding that will help to identify exotic quantum states, RIKEN physicists have seen strongly competing factors that affect …

Two-dimensional materials and interfaces can convert spin current into a vortex of charge current

“Low-power information processing could be possible using a new method for converting between spin and charge currents Energy-efficient spintronic devices are closer to being realized thanks to a new mechanism predicted by RIKEN physicists for converting between electrical current vortices …

Engineering matter at the atomic level

“As devices continue to be built on an increasingly small scale, scientists are looking toward developing ways to engineer materials at the atomic level. In a breakthrough that will contribute to this, published in Nature Communications, researchers from the RIKEN …

Giant radio pulses from pulsars are hundreds of times more energetic than previously believed

“A group led by scientists from the RIKEN Cluster for Pioneering Research, using coordinated observations of the Crab pulsar in a number of frequencies, have discovered that the “giant radio pulses” which it emits include an increase in x-ray emissions …

Thin cuprous iodide film will enable better optoelectronic devices

“A defect-free thin film of cuprous iodide—made up of just one crystal—has been fabricated by RIKEN physicists1. The atomically flat sample is a boost for producing better semiconductors. Semiconductors lie at the heart of many optoelectronic devices including …

A shapeshifting material based on inorganic matter

“By embedding titanium-based sheets in water, a group led by scientists from the RIKEN Center for Emergent Matter Science has created a material using inorganic materials that can be converted from a hard gel to soft matter using temperature changes …

Dark-matter candidate could display stringy effects in the lab

“Calculations show how theoretical ‘axionic strings’ could create odd behavior if produced in exotic materials in the lab A hypothetical particle that could solve one of the biggest puzzles in cosmology just got a little less mysterious. A RIKEN physicist …

Researchers find “missing link” between magnetars and rotation-powered pulsars

“Researchers from the RIKEN Cluster for Pioneering Research have made observations of a new magnetar, called Swift J1818.0-1607, which challenges current knowledge about two types of extreme stars, known as magnetars and pulsars. The research, just published in The …

Japan’s Fugaku gains title as world’s fastest supercomputer

“The supercomputer Fugaku, which is being developed jointly by RIKEN and Fujitsu Limited based on Arm® technology, has taken the top spot on the Top500 listThe webpage will open in a new tab., a ranking of the world’s fastest …
