What Quemix does
Quemix Inc. is a Tokyo-based quantum computing software company founded in June 2019 and consolidated under publicly listed parent Terrasky Co., Ltd. The company develops proprietary algorithms for fault-tolerant quantum computers (FTQC), with its core commercial product being Quloud, a cloud-based materials calculation platform accessible via web browser that integrates multiple computational engines (RSDFT, OpenMX, Quantum ESPRESSO, LAMMPS, FLARE) and proprietary modules including Quloud-Mag for first-principles magnetic material simulation. The technical differentiators are in-house patented and patent-pending quantum algorithms, most notably PITE® (Probabilistic Imaginary-Time Evolution) with mathematically proven quantum speedup for ground-state calculations, POD Readout which reduces quantum measurement count by up to 1/1000, and QAVG for high-precision quantum phase estimation in materials simulation. The engineering team is led by CEO Yuichiro Matsushita (PhD Engineering, University of Tokyo; former Max Planck Institute) and includes a 2011 ACM Gordon Bell Award winner as Head of Product Development.
Quemix generates revenue through four streams: Quloud subscription (tiered academic and general plans with annual contracts), a Quantum Technology Support Program (consulting, use-case development, joint research support), contracted materials calculation services, and joint R&D partnerships with major Japanese corporates. The company maintains joint development relationships with at least nine Japanese enterprise partners spanning automotive (Honda, Nissan, Toyota, Denso), materials and chemicals (Sumitomo Rubber, Mitsui Mining, NGK), and IT services (SCSK), often producing co-authored patents and peer-reviewed publications. GTM is sales-led, combining direct enterprise engagement, SCSK channel partnership for materials informatics, and thought-leadership channels including the Q2B Tokyo conference (co-hosted and platinum sponsored) and academic seminars.
Recent strategic momentum includes a November 2024 capital and business partnership with SCSK Corporation, an April 2025 funding round of approximately $3.83M from Mizuho Capital, Mizuho Leasing, SCSK, Terrasky and YNF, four Quloud platform releases between November 2023 and December 2025, and a cluster of major partnership announcements in June 2026 covering DFT acceleration with Honda Research Institute, aerodynamic simulation with Nissan, and quantum measurement-bottleneck breakthroughs. The company has obtained ISO/IEC 27001:2022 certification and targets practical FTQC implementation for materials calculation and simulation by 2030.
