Explore Plaquette licensing

Plaquette is a Python software suite. Product documentation directs users to discuss licensing or book a demo; its public technical paper can be read without a software license.

DOCUMENTED EVIDENCE

What the sources establish

A July 2026 preprint validates simulation methods against full-state reference calculations for selected noise models. Yaqumo separately confirms adopting Plaquette to evaluate its neutral-atom architecture.

What remains unresolved

Predicted logical error rates depend on the hardware model and simulation assumptions. Software adoption and simulated fault tolerance do not establish a working fault-tolerant quantum computer.

The next question to watch

How closely will the model's predicted logical error rates and resource requirements match measured hardware as systems scale?

A research question, not a promised milestone.

Open research questions

Editorial questions for this profile. No reviewed closure decision has been recorded; unanswered questions do not lower the official score.

Open research question

How closely will the model's predicted logical error rates and resource requirements match measured hardware as systems scale?

What evidence would help

A source addressing this question must identify the named system, experiment or deployment, its conditions, measured outcome and remaining limitations. What are the physical-qubit, runtime and sampling overheads?

What would resolve it?

An editorial review must explain which part of this question the evidence resolves. A roadmap or an announcement alone does not close it.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.

Suggest evidence
Open research question

Which named system or service can I use under the documented access route?

What evidence would help

Check the current terms for explore plaquette licensing. Identify the system version, eligibility, restrictions and whether the result used hardware or simulation.

What would resolve it?

Current primary documentation must identify the offering, eligible user and access conditions. An unspecified company-level access claim is insufficient.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.

Suggest evidence
Open research question

Was error suppression measured on hardware or predicted by simulation?

What evidence would help

Provide the source location, relevant product or generation, workload, resource constraints and reported uncertainty. Keep measurements, simulations and announced targets distinct.

What would resolve it?

A source reviewer must map the evidence to this exact scope. Missing disclosure remains unknown; it is not technical failure.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.
