Control-Plane Openness in Near-Term Quantum Computing: A Survey of Vendor Stacks and Field Implications

Rylan Malarchick

Access to the control plane in commercial quantum computing has bifurcated, with large superconducting platforms closing it and mid-tier plus neutral-atom vendors opening it.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Public access to pulse-level and control-electronics interfaces in commercial quantum computing has bifurcated, with the largest superconducting cloud platforms closing access while mid-tier superconducting vendors and neutral-atom platforms have moved toward greater openness.

C2weakest assumption

The six-axis grading of each vendor accurately reflects current public policies and technical capabilities without requiring private vendor information or post-survey policy changes.

C3one line summary

A survey of thirteen quantum vendors grades control-plane openness on six axes and ships a machine-readable catalog documenting the bifurcation in access.
