However, the operation of the classical user, which involves measurement and resending using the Single-state protocol, presents technical difficulties in experiment and there is a security vulnerability of \"tagged\" attack in theory. To solve these problems, in our work, based on the Single-state protocol, we propose the \"selective modulation\" method and successfully implement a phase-encoded semi-q","authors_text":"Jindong Wang, Naida Mo, Qincheng Hou, Siying Huang, Tianming Zhao, Yafei Yu, Zhengjun Wei, Zhiming Zhang","cross_cats":["physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-05-13T05:10:30Z","title":"Phase coding semi-quantum key distribution system based on the Single-state protocol"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2405.07469","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:ab2c74ae9a58ee25fe1d636c9ffff875f62529e460c1dacf838b5dd35df55ae7","target":"record","created_at":"2026-05-22T01:04:53Z","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":"b01536849ae7f883aa7641aea6c6e78be596911bbccdbdfbfefa2c3ca9bbcd0f","cross_cats_sorted":["physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-05-13T05:10:30Z","title_canon_sha256":"e730f2d71f8c9cb9cf023d261f90a8e40b781fafd8054b9bf12f008bc51589ac"},"schema_version":"1.0","source":{"id":"2405.07469","kind":"arxiv","version":2}},"canonical_sha256":"2b674496cffa9bc8a460c5f1c17dbb377e0c6cd33e96f2b3230ceae675162a39","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2b674496cffa9bc8a460c5f1c17dbb377e0c6cd33e96f2b3230ceae675162a39","first_computed_at":"2026-05-22T01:04:53.110503Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-22T01:04:53.110503Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pzwkKjkjS10c5QboAh+zNkdy+QEC6dV4ImSq8OT6+0NFFNWcSkr7402XKNIluCPVeeDTdxGG4WEETDVLU+4oBQ==","signature_status":"signed_v1","signed_at":"2026-05-22T01:04:53.111286Z","signed_message":"canonical_sha256_bytes"},"source_id":"2405.07469","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ab2c74ae9a58ee25fe1d636c9ffff875f62529e460c1dacf838b5dd35df55ae7","sha256:0fc8ec39d5325b059231885c443c6778c2a759ccd0d9b478e413639b4f7cbb88"],"state_sha256":"436a49e737c2a7ed63611f8801a7e649f8483a847d43b5abfc2cca400dad31a7"}
