Atom replacement extends a toric-code memory experiment
A dated, source-bounded reading of the original report.
Atom replacement extends a toric-code memory experiment
- Reported
- Atom Computing and collaborators report toric-code memory experiments with replacement atoms and repeated reservoir reloading.
- Supported observation
- The smaller code ran for up to 90 syndrome-extraction cycles; the larger code reached 70. Storage-zone atoms were replenished every tenth cycle.
- Conditions
- The preprint compares codes using 16 data plus 16 ancilla qubits and 32 data plus 32 ancillas. Recorded measurements were decoded with PyMatching using loss-aware reweighting. Long runs and the short-run code-size comparison are separate datasets.
Not established
The 90-cycle result does not demonstrate indefinitely accurate computation or universal fault tolerance. Lower error for the larger code in short runs must not be generalized to the deep-run results.

What would change this record?
More code sizes and longer runs with full error distributions, coherent-error treatment and documented logical operations.
