Fujitsu quantum-inspired technology
It is expected to take time to apply quantum computing to practical problems. Here we introduce Fujitsu Digital Annealer, a Quantum-Inspired technology currently available that specializes in combinatorial optimization problems.

The Fujitsu High-Performance Computing, exemplified by the world's fastest Fugaku supercomputer, has demonstrated impactful results in various fields, including life sciences, disaster prevention and mitigation, energy, manufacturing, basic science, and socio-economic applications. Our mission is to surpass the limits imposed by Moore's Law and von Neumann's bottleneck, pushing the boundaries of cutting-edge computing technologies.
As the Fujitsu research center for advanced computing in North America, we are forging collaborations with the University of Toronto and other leading universities in North America. Together, we aim to usher in a new era of computing power, supporting and driving future innovations.
