What Quantum Rings does
Quantum Rings, Inc. is a Boulder, Colorado-based quantum computing software company founded in 2023 by Bob Wold and Venkateswaran Kasirajan. The company develops the Quantum Rings SDK, a Python-based quantum circuit simulation toolkit that uses a proprietary state compression method to execute hundreds of qubits and millions of gate operations on standard hardware (CPU and GPU), reportedly achieving an average 0.678 XEB fidelity score against Google's Sycamore supremacy circuits using only 32GB of memory. The SDK integrates with NVIDIA CUDA-Q, the Qiskit ecosystem (via a native Toolkit supporting Sampler/Estimator primitives and Qiskit 1.x/2.x libraries), OpenQASM 3, and PennyLane.
In December 2025, the company expanded beyond simulation by launching the Open Quantum platform, a hardware-agnostic cloud service providing unified API access to real quantum processors from IonQ, IQM, Rigetti, AQT, and Quantinuum. The SDK is distributed free for non-commercial and academic use via pip, Google Colab, the qBraid marketplace, and NVIDIA's CUDA-Q platform; enterprise licenses are sold for commercial use, and Open Quantum operates a usage-based credit system with a $50 free tier refreshed every 90 days. The company serves academic researchers, quantum software developers, and enterprises exploring commercial quantum applications, with adoption evidenced by 250+ universities, 10M+ circuits executed, and endorsements from ASU, NVIDIA, AWS, UChicago, and CU Boulder. Quantum Rings is a member of both U.S. Quantum Hubs (Elevate Quantum in Colorado and Chicago Quantum Exchange in Illinois) and was a member of Duality Accelerator Cohort 4.
