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.

QunaSys, a leading innovator in quantum-chemistry software with a Japan–Europe footprint, and Hon Hai Research Institute, the research arm of Hon Hai Technology Group (Foxconn), today announced the acceptance of their joint research paper “Neural Network Assisted Fermionic Compression Encoding: A Lossy-QSCI Framework for Scalable Quantum Chemistry Simulations” in Physical Review Research.

QunaSys is thrilled to announce that the QuEnAIS Consortium, comprising Cortex Discovery, Fraunhofer ITWM’s High Performance Computing (HPC) department and QunaSys, has been awarded a grant under the EUREKA Applied Quantum Call for a Quantum-Enhanced Drug Discovery Project. This grant will support the development of an innovative computational pipeline that aims to revolutionize drug discovery by combining advanced artificial intelligence (AI) algorithms, HPC techniques, and near-term quantum computing technologies.

QunaSys Inc. (Headquarters: Bunkyo-ku, Tokyo; CEO: Tennin Yan; hereinafter “QunaSys”), a company specializing in quantum computing software and algorithm development, releases its inaugural quantum computer benchmark report, “QURI Bench” (preview version), on May 12, 2025, via its official website. This benchmark independently evaluates the performance and characteristics of various quantum hardware platforms. The official version of “QURI Bench” is scheduled for release in July 2025.
