Before Kyon could route any customer's work to quantum hardware, we had to answer a harder question: which hardware actually performs? We ran a systematic head-to-head bake-off across three major cloud quantum providers — IBM Brisbane (127-qubit Eagle), IonQ Forte Enterprise (trapped-ion via AWS Braket), and Rigetti Cepheus-1 (108-qubit via AWS Braket) — using Bell state fidelity as the standardized benchmark. The winner would be featured in our first advertising campaign.

Topics covered:

- What Bell state fidelity is and why it predicts real algorithm performance

- Why IonQ Forte Enterprise won at 98.7% fidelity — and why it wasn't close

- How a 6-node Max-Cut problem returned 100% optimal results on live quantum hardware

- Where IBM Brisbane and Rigetti Cepheus-1 stood in the comparison

- What the entire bake-off cost (under $125) — and what that says about cloud quantum access in 2026

- The gap between "quantum hardware exists" and "quantum hardware solves your problem," and how Kyon closes it
