The protocol is performed through bi- and tripartite entangled channels of discrete variables and qubits encoded in polarization of individual photons. The experimental results demonstrate successful controlled quantum teleportation with a fidelity around $83\\%$, well above the classical limit. By realizing the controlled quantum teleportation through biseparable state, we show that tripartite entangled is not a necessary resource for controlled quantum teleportation and the ","authors_text":"Anton\\'in \\v{C}ernoch, Artur Barasi\\'nski, Karel Lemr","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2019-03-26T13:38:26Z","title":"Demonstration of quantum controlled teleportation for discrete variables on linear optical devices"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.10881","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":"sha256:75d63b9a6b8d9cf8bbfacfd4034d1b2db7779efd995548e61007f0e24e3d6cf9","target":"record","created_at":"2026-05-17T23:50:17Z","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":"aedfb850e7bb36cd0de2206a89be02e5ae92c87a74098c4b08e4c1223ab3379d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2019-03-26T13:38:26Z","title_canon_sha256":"01fbca2bf8d2c5951189a1e022956edd44fd1e9c46f5ef25be486b9d4e08c06c"},"schema_version":"1.0","source":{"id":"1903.10881","kind":"arxiv","version":1}},"canonical_sha256":"3954a3064fe17675674053d6536f0c1e576cb81c9703186d98ba23abf093c968","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3954a3064fe17675674053d6536f0c1e576cb81c9703186d98ba23abf093c968","first_computed_at":"2026-05-17T23:50:17.388737Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:50:17.388737Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"b7hmm8deaS063STeFFhLTFR/R1DGXZc7XzeC6LvQIS2doKjPUrz3ZDu2k2qT/MeEdlMdPvhTx5Za8EWh+hWgCQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:50:17.389543Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.10881","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:75d63b9a6b8d9cf8bbfacfd4034d1b2db7779efd995548e61007f0e24e3d6cf9","sha256:eda0368a44975ff467db22c6e98af45de8d9243ac7030b1d803c1a53655cf7fc"],"state_sha256":"306326daf2b4b26ae7be7e1d5919298bb607b59faa8a0c3edd4379a1b6c4fec1"}
