Microsoft, Atom Computing and EeroQ publish new progress updates on quantum computing

The quantum computing field is back in the spotlight after progress updates published by three different companies in recent weeks. The updates conveyed by Ars Technica show the concrete results of long-running technical work at Microsoft, Atom Computing and EeroQ across different qubit technologies.

Microsoft's update showed that years of research on topological qubit technology have produced a first error-correction demonstration. The company described a milestone of 'logical qubit' stability on experimental devices that work with quantum states known as Majorana zero modes (MZM). Microsoft Quantum's chief scientist Krysta Svore said, 'we are holding in our hands the first data set demonstrating the practical stability of a topological qubit'.

Atom Computing shared its progress on neutral atom technology. The company announced that it had kept a system of 1,180 physical qubits operational within a grid of laser-trapped neutral atoms. That number is above the 1,000-qubit threshold reached last year and is the world's largest operational system based on a neutral-atom quantum computer.

EeroQ shared a new stability test for its electron-based, helium-surface qubit technology. The company announced that the quantum-state stability of a single electron held at the helium surface has been raised to the second range. That figure represents a thousandfold extension over the millisecond-range stability typical of most quantum systems.

The three approaches imply different technical trade-offs. Microsoft's topological qubit offers an inherently error-resistant quantum state, requiring fewer error-correction layers per 'bare qubit'. Atom Computing's neutral-atom approach offers a broadly scalable grid architecture. EeroQ's helium-based approach lays the groundwork for a quantum computing platform operable at near-room-temperature conditions.

Ars Technica's science editor John Timmer said, 'three different approaches sharing updates in the same week shows that the sector is approaching a long-anticipated turning point; which of the three approaches will deliver a practical quantum advantage remains an open question'. Timmer predicts that thematic comparisons across the sector will multiply in the coming year.

The US Department of Energy (DOE) Office of Science program confirmed that all three companies are recipients of federal research funding at different levels. Microsoft received a 110 million dollar grant under DOE's Quantum Information Edge Initiative. Atom Computing received a 65 million dollar award under DOE's Quantum Initiative. EeroQ enters a collaboration with Argonne National Laboratory through a smaller 12 million dollar grant.

Commercial stakeholders in the quantum computing market are watching closely. JPMorgan Chase, Goldman Sachs and Boeing have reportedly launched quantum computing pilot projects for financial modelling and aerospace design. Dr Yujin Ben, who leads Goldman's quantum computing team, told Ars Technica, 'within the next three years we plan to launch quantum advantage tests for pricing models'.

There is also a warning against inflated or hyped claims in the quantum field. Caltech quantum information theorist Professor John Preskill said, 'one must look carefully at the metrics that companies share; logical qubit stability is a concept that varies according to the layered error-correction architecture in use'. Preskill's 2018 coinage 'Noisy Intermediate-Scale Quantum' (NISQ) remains the standard reference in the field.

Ars Technica's reporting underscores that the latest updates from the three companies represent a step forward for the sector but that reaching practical quantum computing advantage remains a multi-year technical and engineering path. In the second half of 2026, these three companies are expected to share additional demonstrations, partnerships and results; sector analysts are scheduling their calendars accordingly.
