Rev. Lett. 116, 020503 (2016), has been considered as a practical measure of non-Markovianity. In this paper, we utilize an all-optical scheme to simulate a non-Markovian collision model and to examine how Gaussian steering can be used as a tool for quantifying the non-Markovianity of a structured continuous variable (CV) Gaussian channel. By modifying the reflectivity of the beam splitters (BSs), we are able to tune the degree of non-Markovianity","authors_text":"Jiasen Jin, Xingli Li, Yan Li","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-02-01T11:46:41Z","title":"Witnessing non-Markovianity with Gaussian quantum steering in collision model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2402.00524","kind":"arxiv","version":2},"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":"sha256:6311e9b09bc3a6d5886f6de8e82d9169b627b7e8f3ded6b40ce670bcb71821bc","target":"record","created_at":"2026-07-05T08:14:21Z","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":"9f2b9faa53a9f2d43eec10bf40d5360c057cc25191e07371a0d77517c7a45f3f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-02-01T11:46:41Z","title_canon_sha256":"6c26f333a5d5426ee9feeffef8cfda3f1002fb9fad2fa61b5c044020b906a9d7"},"schema_version":"1.0","source":{"id":"2402.00524","kind":"arxiv","version":2}},"canonical_sha256":"ff1dce250c5b935f0791bfa01300dcbc0cd76d798eccd5becee9150e1961040a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ff1dce250c5b935f0791bfa01300dcbc0cd76d798eccd5becee9150e1961040a","first_computed_at":"2026-07-05T08:14:21.674394Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:14:21.674394Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4jyDIiEAFii/LiRicqKmyPyeoCQ2xSfyE3f2XRPTZUYv8kUqstmz+E+esVYBpJwZTE/uu6XGwftBWRIGGI1WCw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:14:21.674898Z","signed_message":"canonical_sha256_bytes"},"source_id":"2402.00524","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6311e9b09bc3a6d5886f6de8e82d9169b627b7e8f3ded6b40ce670bcb71821bc","sha256:1526ed99db79736cef8b9f07e4211a10327a5ba7ef99698b32bf02d5dbadd3c1"],"state_sha256":"9e8f4417b0d455ab124902c39c53a5971c08ef0ef776dc953621a6d4e2f41486"}
