DOCUMENTED EVIDENCE

What the sources establish

Quantonation reported a completed €220 million second-fund close on 18 February 2026, with 12 investments already made by that fund. Qblox separately confirms Quantonation co-led its completed $26 million Series A in June 2024.

What remains unresolved

Fund size and portfolio breadth establish financing activity, not realized returns, successful commercialization or quantum advantage. The portfolio also includes businesses outside quantum computing.

The next question to watch

Which portfolio companies can document repeatable customer deployment and sustained commercial adoption beyond research partnerships?

A research question, not a promised milestone.

QubitWire coverage

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

Which portfolio companies can document repeatable customer deployment and sustained commercial adoption beyond research partnerships?

What evidence would help

A source addressing this question must identify the named system, experiment or deployment, its conditions, measured outcome and remaining limitations. Do named recipients confirm the support or program outcome?

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 the portfolio. 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

Does the organization support your stage, geography and technology?

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.
