EeroQ

EeroQ develops quantum hardware using electrons held above superfluid helium. Its control-chip approach uses established semiconductor fabrication and mobile electrons, aiming to connect storage, gate and readout locations without a dedicated control wire for every electron.

What it does. Where it fits.

Electrons above superfluid helium with CMOS-fabricated control chips; long-term electron-spin computation.

Who should look closer

Editorial assessment: Researchers comparing alternative solid-state architectures and the engineering of mobile qubits, especially the distinction between moving charge and preserving quantum information.

DOCUMENTED EVIDENCE

What the sources establish

A July 2026 company announcement describes publication of selective two-dimensional electron shuttling on the Wonder Lake chip in Physical Review Applied. The reported experiment concerns charge transport and addressing, rather than a complete spin-qubit processor.

What remains unresolved

Addressable electron capacity, retained charge and a quantum gate have different meanings. The control architecture does not itself establish spin-preserving computation, a logical-qubit count or application advantage.

The next question to watch

Can the transport platform support measured spin initialization, coherent operations and readout while preserving quantum information through repeated movement?

A research question, not a promised milestone.

QubitWire coverage

No published QubitWire stories currently match this organization. The evidence sources below provide the starting point.

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

Can the transport platform support measured spin initialization, coherent operations and readout while preserving quantum information through repeated movement?

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.

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 research and partnership enquiries. 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 result report errors, circuit depth and a credible classical baseline?

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.
