Atom replacement extends a toric-code memory experiment

A dated, source-bounded reading of the original report.

BREAKTHROUGH LEDGER · quantum 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.
