Key elements of FTQC such as error-correcting codes and decoding are supported by a rich bed of stabilizer simulation software such as Stim and CHP, which are essential for numerically characterizing these protocols at realistic scales. Recently, experimental groups have built nascent high-dimensional quantum hardware, known as qudits, which have a myriad of attractive properties for algorithms an"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"We introduce the first open-source realization of such a simulator for all dimensions.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the qudit stabilizer formalism admits an efficient simulation algorithm whose implementation matches the underlying physics for all tested dimensions and circuit sizes.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Sdim is the first open-source qudit stabilizer simulator supporting all dimensions, enabling circuit evaluation and sampling for qudit fault-tolerant quantum computing research.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Sdim provides the first open-source stabilizer simulator that works for qudits in any dimension.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"ef28d0bd25f9fdb65d71333a4e47d3d1bee0827f0badfc48b99f5a3815bdc090"},"source":{"id":"2511.12777","kind":"arxiv","version":2},"verdict":{"id":"52c66ce9-ff84-4c6e-98a3-507fd10ba38a","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-17T21:33:13.630334Z","strongest_claim":"We introduce the first open-source realization of such a simulator for all dimensions.","one_line_summary":"Sdim is the first open-source qudit stabilizer simulator supporting all dimensions, enabling circuit evaluation and sampling for qudit fault-tolerant quantum computing research.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the qudit stabilizer formalism admits an efficient simulation algorithm whose implementation matches the underlying physics for all tested dimensions and circuit sizes.","pith_extraction_headline":"Sdim provides the first open-source stabilizer simulator that works for qudits in any dimension."},"references":{"count":79,"sample":[{"doi":"","year":2004,"title":"Scott Aaronson and Daniel Gottesman. 2004.
