The defining feature of the Stim format is the REPEAT block. This allows for the archival of repetitive QEC cycles (e.g., a surface code performing 10,000 error correction rounds) without requiring millions of lines of code.
Mara became an intermediary. She carried smiles into hospice rooms in the form of small, curated stims: the memory of a parade she had borrowed earlier, a child’s triumphant shout from a file she no longer needed. In exchange, she asked for the traces of the XR file. People gave because they wanted to be whole, or because they could not bear some memory any longer. She crafted exchanges like a paper conservator: matching tonalities, temperaments, the precise cadence of grief to ensure an even ledger. stim file archive
