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.

The official site describes a hardware-development program and a contact route. A generally available quantum-computing service is not established by these sources.
Check the current access route ↗What has been demonstrated
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
