Research at Scale, Without the Wait

Accuracy you can publish and repeatability your reviewers expect — at a scale that fits how research actually runs: on your laptop, on your cluster, under SLURM, thousands of experiments at a time.

Why Quantum Rings

Built for researchers

Accuracy Worth Publishing

High-fidelity, repeatable results — your code is the only variable. The same engine behind our arXiv papers on Google’s supremacy circuits.

Built for Your Cluster

Runs anywhere Python runs. Schedule under SLURM and fan out thousands of parallel experiments across your research cluster.

One Node, Datacenter-Class Reach

Do more on a single node than statevector simulation can do with an entire datacenter — hundreds of qubits, millions of operations.

  • Free for academic use
  • SLURM-friendly on research clusters
  • Works with Qiskit & CUDA-Q
  • Real QPUs via Open Quantum — $50 in free credits every 90 days

Published research

Backed by Published Research

Our claims aren’t marketing — they’re published, with methods and numbers anyone can check. We simulate Google’s “quantum supremacy” circuits on accessible hardware, with the fidelity and speedups to prove it.

Revisiting Quantum Supremacy: Simulating Sycamore-Class Circuits Using Hybrid CPU/GPU HPC Workloads

B. Wold, V. Kasirajan

A hybrid NVIDIA A100 GPU + parallel-CPU pipeline simulates the 53-qubit, 20-cycle Sycamore circuit in 1h 15m — a 6.95×10⁷ speedup over Google’s original 10,000-year classical estimate — at 0.549 XEB fidelity, 274× Google’s reported 0.002.

Empowering Large-Scale Quantum Circuit Development: Effective Simulation of Sycamore Circuits

V. Kasirajan, T. Battelle, B. Wold

Google’s random-circuit-sampling “quantum supremacy” circuits simulated with high fidelity on classical systems commonly available to developers — an average XEB score of 0.678, exceeding values reported for the same circuits.
