QC Ware is a Palo Alto-based enterprise software company that builds quantum and quantum-inspired tools for hard scientific problems. Founded in 2014 by veterans of NASA Ames, it started as a hardware-agnostic quantum cloud platform (Forge) and evolved into Promethium, a GPU-accelerated quantum chemistry SaaS that runs density functional theory calculations on molecules up to thousands of atoms, claiming speeds 10 to 100 times faster than legacy tools. The company also runs Q2B, the largest annual practical quantum computing conference, and counts Goldman Sachs, Airbus, BMW and Covestro among its collaborators and investors.
BlueQubit is a San Francisco quantum-software startup founded in 2022 by Hrant Gharibyan and Hayk Tepanyan. Its Quantum-Software-as-a-Service (QSaaS) platform lets engineers write algorithms in familiar frameworks like Qiskit, Cirq and PennyLane and run them - with a single click - on GPU-based emulators the company says run up to 100x faster than common alternatives, or on real quantum hardware such as IBM's Heron and Quantinuum's H2. The company raised a $10M seed round in December 2024 and works with partners including IBM, NVIDIA, Quantinuum, Honda, AWS and Stanford. Its stated goal is to democratize quantum computing and make it practical for real-world enterprise applications.
Haiqu is a quantum software company building a hardware-aware operating system that helps enterprise and scientific R&D teams run larger, more useful workloads on today's quantum computers - without waiting for fully fault-tolerant machines. Its full-stack platform combines agentic R&D tooling, an optimization SDK, and a runtime that the company says can cut quantum execution cost and time by orders of magnitude. Founded in 2022 and backed by an $11M seed round led by Primary Venture Partners, Haiqu works with early enterprise users including Capgemini, HSBC, BMO, Airbus, and Deloitte.
