We develop quantum computing architectures scalable by design. By leveraging a unique control setup, our chip technology keeps wiring requirements at a constant, manageable level, regardless of the number of qubit. By decoupling control and performance, it accelerates the development of practical quantum computers on the most advanced qubit platform. With over two decades of experience in quantum technologies and materials science, since 2023 weve proudly built within a world-class ecosystem.

Axiomatic_AI is readying to launch with the aim to accelerate R&D by "Automated Interpretable Reasoning" (AIR) -- a verifiably truthful AI model built for reasoning in science and engineering. Axiomatic_AI is hiring top talent interested in a future of human reasoning aided by -- not replaced by -- AI, and a future that empowers a new generation of innovators to solve important problems thro The Challenge and Opportunity: Mission 10X30 - Pioneering a Tenfold Boost in Science & Engineering Productivity by 2030 At the heart of our mission lies the ambition to create software and algorithms that not only automate processes but also provide clear, understandable insights to fuel innovation and research. Our aim? To achieve Mission10X30, a bold vision aiming for a tenfold decrease in the time engineers spend tackling technical challenges by 2030. How? Through our groundbreaking AI-engineering tool - Axiomatic AI. This tool is designed to streamline end-to-end prototype development, with a primary focus on the largest segments of semiconductor-based hardware. Background: The scientific method stands as one of humanitys most remarkable achievements, guiding us through a journey of understanding via iterative experimentation and evidence-driven deduction. In a mere fraction of Earths history - less than 0.001% - this methodology has propelled us from the Industrial Revolution to the digital age. Now, with the emergence of artificial intelligence, we stand at a crossroads: a future where AI replaces humans, or one where AI empowers us through Automated Interpretable Reasoning. Our Unique Approach: Axiomatic AI introduces a novel methodology grounded in evidence-driven deduction, deeply rooted in the fundamentals of physics and engineering knowledge. Our goal? To showcase the practicality of axiomatic AI through demonstrative projects, starting with physics and engineering domains. Unlike conventional black-box AI, our approach offers transparency and interpretability.
