It is found that the unidirectional interaction prolongs the lifetime of the target excited state, thereby suppressing the magnon re-excitation and promoting both the average purity and number of two-magnon bundles. Consequently, the chiral interaction not only offers directional control but also improves the quality of the multi-magnon source, which may find potential applications in quantum information processing.","authors_text":"Chengdeng Gou, Deyi Kong, Fei Wang, Xiangming Hu, Zhicai Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-07-02T03:06:20Z","title":"Chiral interaction enhanced magnon bundle emission"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.01635","kind":"arxiv","version":1},"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:de24df1f1dfea302aada1cc390bf204fd06c179c6bcb371187cf75af05736ea0","target":"record","created_at":"2026-07-03T01:17:04Z","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":"58d46efc9e00a3a70ab02040297b4137e809a35be20bf4482e38a128e8dc5e30","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-07-02T03:06:20Z","title_canon_sha256":"b2c51c3bda2af5936a98aaef565b91f229fbd617bd81ba396ab66134f37b83e5"},"schema_version":"1.0","source":{"id":"2607.01635","kind":"arxiv","version":1}},"canonical_sha256":"819c30e25b7cdda9f81937f7c4c12c389c2ba5392bcbac3c366f61e1d42014de","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"819c30e25b7cdda9f81937f7c4c12c389c2ba5392bcbac3c366f61e1d42014de","first_computed_at":"2026-07-03T01:17:04.050907Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-03T01:17:04.050907Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9124537PwFegv+FNZ2LsoeKMtpyg1hRSbUGK7W6OYxJuLv0FO8qkBD5dCeHXI6TtdBPsBozn7mxadA9XYwAUCg==","signature_status":"signed_v1","signed_at":"2026-07-03T01:17:04.051305Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.01635","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:de24df1f1dfea302aada1cc390bf204fd06c179c6bcb371187cf75af05736ea0","sha256:c2c2752d57680a1794f8351b86867284aeea0eba135945f9be0b4842e71308c3"],"state_sha256":"71fed47ecbd2cd8ed1ffc4a91121d4231596c5e9de846bcd71e1c46942332361"}
