Braiding and fusion provide a gate-set demonstration
A dated, source-bounded reading of the original report.
Braiding and fusion provide a gate-set demonstration
- Reported
- Lo and colleagues report a universal topological gate set using braiding and fusion on Quantinuum H2.
- Supported observation
- The checked v2 preprint prepares a 54-qubit S3 topologically ordered state, encodes logical qutrits and demonstrates magic-state preparation.
- Conditions
- The experiment combines braiding with charge measurements. Magic-state preparation postselects specified fusion outcomes, so accepted shots are conditional results. The record concerns demonstrated operations within a programmed trapped-ion system, not a comparison with commercial fault-tolerant computers.
Not established
This proof of principle does not establish scalable fault tolerance or an application advantage. The journal version was inaccessible; this assessment is limited to the inspected preprint.

What would change this record?
Larger systems with measured logical errors, decoding performance and total resources, including rejected shots.
