Ibm Delivers Quantum System Two To Riken In Japan Integrating With

KOBE, Japan, June 23, 2025 /PRNewswire/ -- IBM (NYSE: IBM) and RIKEN, a national research laboratory in Japan, today unveiled the first IBM Quantum System Two ever to be deployed outside of the United... The availability of this system also marks a milestone as the first quantum computer to be co-located with RIKEN's supercomputer Fugaku — one of the most powerful classical systems on Earth. This effort is supported by the New Energy and Industrial Technology Development Organization (NEDO), an organization under the jurisdiction of Japan's Ministry of Economy, Trade and Industry (METI)'s "Development of Integrated Utilization Technology for... IBM Quantum System Two at RIKEN is powered by IBM's 156-qubit IBM Quantum Heron, the company's best performing quantum processor to-date. IBM Heron's quality as measured by the two-qubit error rate, across a 100-qubit layered circuit, is 3x10-3 (with the best two-qubit error being 1x10-3) — which is 10 times better than the previous generation... IBM Heron's speed, as measured by the CLOPS (circuit layer operations per second) metric is 250,000, which reflects another 10x improvement in the past year, over IBM Eagle.

At a scale of 156 qubits, with these quality and speed metrics, Heron is the most performant quantum processor in the world. This latest Heron is capable of running quantum circuits that are beyond brute-force simulations on classical computers, and its connection to Fugaku will enable RIKEN teams to use quantum-centric supercomputing approaches to push forward... The new IBM Quantum System Two is co-located with Fugaku within the RIKEN Center for Computational Science (R-CCS), Japan's premier high-performance computing (HPC) center. The computers are linked through a high-speed network at the fundamental instruction level to form a proving ground for quantum-centric supercomputing. This low-level integration allows RIKEN and IBM engineers to develop parallelized workloads, low-latency classical-quantum communication protocols, and advanced compilation passes and libraries. Because quantum and classical systems will ultimately offer different computational strengths, this will allow each paradigm to seamlessly perform the parts of an algorithm for which it is best suited.

This quantum computer expands IBM's global fleet of quantum computers, and was officially launched during a ribbon-cutting ceremony on June 24, 2025, in Kobe, Japan. The event featured opening remarks from RIKEN President Makoto Gonokami; Jay Gambetta, IBM Fellow and Vice President of IBM Quantum; Akio Yamaguchi, General Manager of IBM Japan; as well as local parliament members and... IBM and RIKEN, a national research laboratory in Japan, have unveiled the first IBM Quantum System Two to be deployed outside of the United States. Located in Kobe, Japan, the system is notably the first quantum computer to be co-located with RIKEN’s Fugaku supercomputer, one of the world’s most powerful classical systems. This deployment, a key milestone for quantum-centric supercomputing, is supported by Japan’s New Energy and Industrial Technology Development Organization (NEDO) as part of the Ministry of Economy, Trade and Industry (METI)‘s “Development of Integrated... The IBM Quantum System Two at RIKEN is powered by IBM’s 156-qubit IBM Quantum Heron processor, which demonstrates significantly improved performance over its predecessor, IBM Quantum Eagle.

Heron achieves a two-qubit error rate of 3×10-3 (with a best of 1×10-3) and a speed of 250,000 CLOPS (Circuit Layer Operations Per Second), representing a 10x improvement in both quality and speed over... The system is co-located with Fugaku within the RIKEN Center for Computational Science (R-CCS) and linked via a high-speed network at the fundamental instruction level, enabling the development of parallelized workloads, low-latency classical-quantum communication... This integration allows RIKEN and IBM researchers to advance quantum-centric supercomputing approaches, pushing research on complex algorithms for problems such as fundamental chemistry. The system is designed to accelerate the discovery of algorithms that can offer quantum advantage, where quantum computers solve problems more efficiently than classical methods. This includes work on sample-based quantum diagonalization (SQD) techniques, which have demonstrated the ability of near-term quantum computers to provide scientific value when combined with powerful classical infrastructure. The installation expands IBM’s global fleet of quantum computers and reinforces Japan’s role in high-performance computing.
