QunaSys Inc.a developer of software and algorithms for quantum computers, has successfully completed end-to-end validation of a quantum algorithm for quantum chemistry that is expected to be useful in fault-tolerant quantum computing (FTQC).

QunaSys Inc. a company specializing in the development of quantum computing algorithms and software, announced that its quantum software development kit “QURI SDK Enterprise” has been officially adopted for RIKEN’s Quantum-HPC Hybrid Platform as part of the “JHPC-quanｚtum” project.

QunaSys Inc. a quantum computing software company headquartered in Tokyo, Japan, has jointly developed two foundational algorithms with Mitsubishi Electric Corporation (“Mitsubishi Electric”) to advance the use of quantum computing in Computer-Aided Engineering (CAE) for product design and development.

Free webinar series: Computation, Data & Quantum
Three Thursdays. Three questions industrial R&D teams are already asking.
If you work with simulation, data, or modeling — and you've wondered where quantum computing actually fits — this is for you.

QunaSys Inc. (Headquarters: Bunkyo-ku, Tokyo; CEO: Tennin Yan; hereinafter “QunaSys”), a company specializing in quantum computing software and algorithm development, announced the launch of a dedicated QSCI technical portal and an official partner program for hardware vendors, marking the next phase in the commercial expansion of its proprietary algorithm, Quantum-Selected Configuration Interaction (QSCI).
Originally published in February 2023 (arXiv: 2302.11320), QSCI has evolved from a research breakthrough into a commercially deployable methodology within quantum–HPC hybrid environments.

QunaSys Europe (QunaSys Denmark ApS) and QunaSys Japan (QunaSys Inc.) are participating in Q-Neko (The Nippon-Europe Quantum Koraborēshon), a major EU–Japan initiative aimed at strengthening collaboration in quantum technologies and high-performance computing (HPC). Through this joint engagement across Europe and Japan, we contribute our expertise in application-driven quantum algorithm development and hybrid HPC+QC integration to accelerate the practical use of quantum technologies in industrial settings.

QunaSys Inc. and SoftBank Corp. have jointly published a new white paper analyzing the practical requirements for applying quantum computing to industrial-scale numerical simulations.
