CHICAGO, July 9, 2026 – EeroQ, the quantum computing company, today announced that its research demonstrating selective two-dimensional shuttling of electrons on superfluid helium has been published in Physical Review Applied, following peer review by the American Physical Society. The paper, “Selective shuttling of electrons on helium using a CMOS control platform,” first shared as a preprint, appears in the journal’s July 2026 issue.

The publication formally validates results EeroQ announced earlier this year: that large numbers of electrons — the company’s qubits — can be selectively addressed and transported across a chip fabricated in a standard commercial CMOS foundry, using a control architecture that requires only a handful of wires. Additionally, this system allows all-to-all connectivity of its qubits, a key quality metric for future large qubit systems.

A central finding of the peer-reviewed work is the remarkable efficiency of fully parallel electron shuttling on the surface of liquid helium. Because the helium surface is atomically smooth and free of the impurities and charge traps found in solid materials, electrons can be moved across the chip with extraordinary fidelity. In the published experiments, EeroQ’s team performed shuttling sequences during which the electrons collectively traveled tens of kilometers across the chip without any detectable loss of charge.

“Publication in Physical Review Applied means these results have stood up to rigorous, independent scrutiny by experts in the field,” said Nick Farina, CEO of EeroQ. “We can move electrons around a chip billions of times, over distances of kilometers in aggregate, and not lose a single one. That kind of lossless transport is exactly what you want from a mobile qubit, the type future quantum computers will be built upon.”

The experiments were performed on EeroQ’s “Wonder Lake” chip, fabricated at U.S. semiconductor foundry SkyWater Technology using its standard 130-nm CMOS process. On the chip, electron packets containing several tens of electrons down to, on average, a single electron are clocked through a two-dimensional network of helium-filled microchannels, in a scheme similar to the charge-coupled devices (CCDs) used in digital imaging. Using just 14 control lines, the team selectively shuttled electrons through any of 128 independently addressable channels, moving them between storage sites and on-chip sensors and bringing packets together at chosen locations.

These operations mirror those needed in a future quantum processor to route qubits to readout and gate zones.

This combination of highly efficient transport and hardware-efficient addressing supports EeroQ’s approach to scalability, in which mobile electron qubits provide all-to-all connectivity across a two-dimensional architecture well suited to all future forms of advanced quantum error correction.
