In this paper we are concerned with the modelling of noise in Noisy Intermediate-Scale Quantum (NISQ) computers. We focus on three error groups that represent the main sources of noise during a computation and present quantum channels that model each source. We engineer a noise model that combines all three noise channels and simulates the evolution of the quantum computer using its calibrated error rates. We run various experiments of our model, showcasing its ","authors_text":"Clive Emary, Konstantinos Georgopoulos, Paolo Zuliani","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2021-01-06T16:04:13Z","title":"Modelling and Simulating the Noisy Behaviour of Near-term Quantum Computers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2101.02109","kind":"arxiv","version":4},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:dbc99f2c7dd925e409a8827139586057e44fe8af37455a8f366ab478da6ae6a3","target":"record","created_at":"2026-07-05T03:41:38Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"a74bae04425bb397e9c19386deaf3b336775710a3be26206b0bb0bf8153bcf94","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2021-01-06T16:04:13Z","title_canon_sha256":"1b9e34de29907461b3553f55bd4dcff84194003c2697c110665fcc852f860670"},"schema_version":"1.0","source":{"id":"2101.02109","kind":"arxiv","version":4}},"canonical_sha256":"b4b8e830b259d86ecde6c66869bd2a9b11117e85ff9029a10a4f70612c787b3e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b4b8e830b259d86ecde6c66869bd2a9b11117e85ff9029a10a4f70612c787b3e","first_computed_at":"2026-07-05T03:41:38.154229Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:41:38.154229Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"raqx3hwaq8/k0YbfjR+nxTKLbIF2h/NyDg8AZbVCfOnAeRRyVpl5a6QVM9DHzNGE7sBm0GhluKhjZoPEwHOIAw==","signature_status":"signed_v1","signed_at":"2026-07-05T03:41:38.154898Z","signed_message":"canonical_sha256_bytes"},"source_id":"2101.02109","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dbc99f2c7dd925e409a8827139586057e44fe8af37455a8f366ab478da6ae6a3","sha256:2f3b5eb51d07254c79b9cf5650b57d677337226f3c52091aa6525d5c7e1ac69f"],"state_sha256":"f30d6c5849af175d2b246d051687c7974e13b61cb3ad576be51c8dd69e01dca1"}
