A research group led by Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences are using an artificial crystal of 30,000 atoms aligned in a cubic array with a spacing of 0.5 micron, cooled to near absolute zero temperature. By manipulating the atoms with a special laser light that blinks for 10 picoseconds, they succeeded in executing quantum simulation of a model of magnetic materials.
Their novel “ultrafast quantum computer” scheme demonstrated last year was applied to quantum simulation. Their achievement shows that their novel “ultrafast quantum simulator” is an epoch-making platform, as it can avoid the issue of external noise, one of the biggest concerns for quantum simulators. The “ultrafast quantum simulator” is expected to contribute to the design of functional materials and the resolution of social problems.
Their results were published online in Physical Review Letters.
Quantum technology, which has seen intensified competition in development in recent years, such as quantum computers, quantum simulators, and quantum sensors, is a qualitatively new technology that takes advantage of the “wave nature” of electrons and atoms. Since quantum technology has the potential to revolutionize functional materials, pharmaceuticals, information security, artificial intelligence, etc., huge investments are being made around the world.
A quantum simulator is a device that simulates the complex behavior of electrons and other microscopic particles in a solid by mapping them onto a highly controllable model material. It is expected to solve problems that would take an infinite amount of time even with the fastest supercomputer, thus bringing about disruptive innovation to solve social problems such as logistics and traffic congestion, and in developing superconductive and magnetic materials.
