Name and period
ID Quantique is an IonQ subsidiary. Its QKD and QRNG products remain listed under the operating brand.
Product scope
Optical QKD systems, quantum random-number generators and quantum-safe key exchange software.

A company profile may discuss several systems. Capabilities remain attached to the product and conditions named in each source; they do not transfer automatically to related organizations. A verified security relationship has not been attached to this record.

TECHNOLOGY & ACCESS

What it does. Where it fits.

Optical QKD systems, quantum random-number generators and quantum-safe key exchange software.

Who should look closer

Optical-network security teams evaluating QKD and device builders sourcing quantum random-number components.

QubitWire’s editorial assessment of practical fit.

Commercial security products

Review the Clavis XG QKD portfolio and request a configuration-specific quote. QRNG products are a separate component offering.

DOCUMENTED EVIDENCE

What the sources establish

IonQ reports ID Quantique supplied Romania's national QKD infrastructure: 36 links spanning over 1,500 km in aggregate. The June 2026 Clavis XG Multiplex launch adds shared-fiber quantum/classical traffic support; this is a company product claim.

What remains unresolved

The Romanian distance is the sum of network links, not one unrepeated quantum transmission. QKD and QRNG serve different functions and neither alone guarantees application security; product assurance must be checked for the exact model and configuration.

The next question to watch

What independently assessable availability, key-management interoperability and security assurance are documented for larger customer networks?

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

What independently assessable availability, key-management interoperability and security assurance are documented for larger customer networks?

What evidence would help

A source addressing this question must identify the named system, experiment or deployment, its conditions, measured outcome and remaining limitations. Is a claim about standards alignment, validation or a completed certification?

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 commercial security products. 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

Which exact algorithm, implementation and version is supported?

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.
