In particular, we investigate the role played by the Gaussian CV states as compared to non-Gaussian states. We find that beam-wandering induced atmospheric losses lead to QKD performance levels that are in general quite different from those found in fixed-attenuation channels. For example, circumstances can be found where no QKD is via","authors_text":"Nedasadat Hosseinidehaj, Robert Malaney","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-05-06T03:23:28Z","title":"CV-QKD with Gaussian and non-Gaussian Entangled States over Satellite-based Channels"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1605.01808","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":"sha256:15f9fae95e644d9c5b28bb9a56ada1320d824bc5f3f6e001340e6c96e8cf28d9","target":"record","created_at":"2026-05-18T00:38:04Z","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":"9ed707bc19f64f06830dc79c677c2a9d7966d67771e1d3883348d95104cf626b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-05-06T03:23:28Z","title_canon_sha256":"f3194b678335e378920d950750292a2d324486190f48960ca01414d83301a8f4"},"schema_version":"1.0","source":{"id":"1605.01808","kind":"arxiv","version":1}},"canonical_sha256":"07517e284315653ef02112174e3409d1ce7cf68733269441d988bfac8f88f531","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"07517e284315653ef02112174e3409d1ce7cf68733269441d988bfac8f88f531","first_computed_at":"2026-05-18T00:38:04.439038Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:38:04.439038Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gw2MURJvsG6xvTn7CbjyeasXKnv7BocY4KyhzdpShdICB7mP5nhUWpQP9dg8K9F+lG9bRKzvearAAKjuKT+hCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:38:04.439787Z","signed_message":"canonical_sha256_bytes"},"source_id":"1605.01808","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:15f9fae95e644d9c5b28bb9a56ada1320d824bc5f3f6e001340e6c96e8cf28d9","sha256:ad03fbe42d3743b31cf7a43b496b57e1c50e25a0198c2712100e0101715e1b8b"],"state_sha256":"b2fb7ebdd16fccac04c08a42b6054b308f509a68bdad479f179d181f765ebc08"}
