Utility Maturity Model for Quantum Platforms — Operating Quantum Computers

The long-term operating goal is not merely to run more circuits. It is to make quantum capability consumable as a governed utility: discoverable, measurable, safe, costed, auditable, and upgradeable. Utility does not mean commodity. It means that consumers can depend on clearly defined contracts while operators manage complexity behind the interface.

Maturity levels

Level	Name	Operating posture
0	experiment	heroic manual execution
1	shared access	basic queues and notebooks
2	managed platform	broker, evidence, policy, and observability
3	productized service	SLAs, support, cost model, replay, release trains
4	governed utility	cross-provider routing, auditable trust, board controls
5	adaptive utility	autonomous optimization with safe rollback and verified guardrails

Level transitions

Transition	Hardest change
experiment to shared access	moving out of notebooks into repeatable workflows
shared access to managed platform	establishing broker, policy, and evidence contracts
managed platform to productized service	making promises and staffing support
productized service to governed utility	operating across providers, audits, and portfolios
governed utility to adaptive utility	allowing automation to act under verified guardrails

The most common false utility is a polished portal over fragile manual work. A portal is useful only when backed by durable contracts, evidence, runbooks, and ownership.

Operating contract closure

A governed utility closes the loop between users, operators, providers, and executives.

Operating rule

A quantum platform becomes a utility when users can consume capability without inheriting uncontrolled uncertainty, and operators can improve the system without breaking trust.
