About

Haiqu develops a full-stack quantum computing software platform described as an "Agentic OS for Quantum R&D teams," enabling researchers to develop frontier quantum applications and run them at scale on any quantum processing unit (QPU). The platform comprises three core layers: an Agentic R&D layer that turns rough ideas into functional prototypes using quantum expertise across theory and hardware-aware algorithmic design; the Haiqu SDK, which provides data loading, circuit compression, error mitigation, and hardware-aware optimization to achieve useful results on today's noisy QPUs; and the Haiqu Runtime, which orchestrates middleware infrastructure and execution flow to reduce time and cost by up to 1,000x. Haiqu supports solutions across finance (quantum Monte Carlo for risk and derivatives modeling), science (quantum simulation for molecular and material systems and drug discovery), engineering (quantum CFD for fluid simulations), AI/ML (quantum machine learning), and logistics (quantum optimization). The platform claims 1M+ data features loadable on 156 qubits and 100x more operations on target hardware. Founded in 2016 and headquartered in San Francisco, California, Haiqu has raised $15 million in a Seed round backed by MaC Venture Capital, Toyota Ventures, Soma Capital, u.ventures, SID Venture Partners, Roosh, Primary Venture Partners, Alumni Ventures, and Collab+Currency.
