About QunaSys
QunaSys is a global leader in Quantum Computing Software, specializing in algorithms that accelerate the discovery of new materials and chemical compounds. Founded in 2018 and based in Tokyo, the company bridges the gap between quantum hardware and industrial application. Its flagship platform, Qamuy™, enables researchers to perform complex quantum chemistry simulations that are beyond the reach of classical supercomputers, focusing on high-impact areas such as battery efficiency, drug discovery, and carbon capture. By May 2026, QunaSys has solidified its role as an ecosystem orchestrator through the QPARC consortium, fostering collaboration between academia and over 50 industrial giants. As a strategic pillar for NIF Security of Critical Technologies and NIF Green Transition and Energy, QunaSys provides the "computational intelligence" necessary for Japan to lead the quantum era. Their business model—a mix of SaaS licensing and high-level R&D consulting—positions them as the essential software layer for the next generation of atomic-scale manufacturing.
