QuamCore is developing a superconducting processor architecture with digital control circuitry operating inside the cryogenic environment. The design targets two scaling constraints: heat dissipated by control electronics and the number of external connections. Its fabrication collaboration with SkyWater focuses on a superconducting single-flux-quantum controller chip, rather than an already operating million-qubit computer. Operational headquarters city not established from reviewed company sources; legal contact is Modiin Maccabim Reut and careers pages mention Herzliya.
Record dates use UTC and show when an assessment or clarification was saved. Review dates show the evidence check. Earlier records were recovered from QubitWire’s source history; no earlier score movement is inferred.

Now
SkyWater confirms a November 2025 contract to co-develop fabrication for QuamCore’s superconducting digital controllers. The announcement places test-vehicle fabrication and cryogenic controller demonstrations in the following 12–18 months; it does not report an operating million-qubit computer.
No dated name or ownership transition is recorded here. An alias is a search aid, not evidence of a legal ownership relationship.
Product scope
Superconducting qubits with cryogenic single-flux-quantum digital control.
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.

Million-qubit density and large cabling reductions are architectural targets. A fabrication collaboration does not prove integrated fault-tolerant computation at that scale.
The next question to watch
Can an integrated cryogenic assembly deliver the proposed controller heat load and qubit-error performance?
A research question, not a promised milestone.

Editorial questions for this profile. No reviewed closure decision has been recorded; unanswered questions do not lower the official score.
Open research question
Can an integrated cryogenic assembly deliver the proposed controller heat load and qubit-error performance?
What evidence would help
A source addressing this question must identify the named system, experiment or deployment, its conditions, measured outcome and remaining limitations. Does the result report errors, circuit depth and a credible classical baseline?
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.
Which named system or service can I use under the documented access route?
What evidence would help
Check the current terms for development partnerships. 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.
Can you access the named system today, and under which plan?
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.
