We establish the security of this protocol against collective attacks which correspond to a linear quantum channel. In particular, all Gaussian attacks are considered in our framework. We show that this protocol outperforms all known practical protocols, even taking into account finite size effects.","authors_text":"Anthony Leverrier, Philippe Grangier","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-05-03T15:55:17Z","title":"Long distance quantum key distribution with continuous variables"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1005.0328","kind":"arxiv","version":3},"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":"sha256:1179ac109ccf2d536e07311ead45a7842d0c8d4b0d6dba99e73db04debb67a1e","target":"record","created_at":"2026-05-18T02:24:09Z","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":"965b87ec15bea9ba59df01c070faef994a94b1e1c69c520b0f6853c4f64b8924","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-05-03T15:55:17Z","title_canon_sha256":"07ca26c122c6dcb3d6bb90c345d6abed5cba128e5da83d207c0b9948c81fadf5"},"schema_version":"1.0","source":{"id":"1005.0328","kind":"arxiv","version":3}},"canonical_sha256":"940369ace4af6ccd24b1f5b8cc61729281aec3b4c602f73b9ec767228a693762","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"940369ace4af6ccd24b1f5b8cc61729281aec3b4c602f73b9ec767228a693762","first_computed_at":"2026-05-18T02:24:09.230414Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:24:09.230414Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"w7okGSnmvoh7J0Y1Im8+W8vLpQQuBCEgsIsLxBzavww+NZoCsvYLgKsRGKeaHdFW4m3Ro0SkS7vMjSjIJ6V3BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:24:09.231098Z","signed_message":"canonical_sha256_bytes"},"source_id":"1005.0328","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1179ac109ccf2d536e07311ead45a7842d0c8d4b0d6dba99e73db04debb67a1e","sha256:2de7e5d55af08c19ceb4ff8a429d95ff202035968a2c79b27318ba7fcb9d0e7a"],"state_sha256":"5ec0c49862683e87618161bd1c1f5278f359ab80dbf76f3771799bd88febd158"}
