Using the electromagnetically induced transparency technique, we show that the three-photon blockade effect can be observed and the properties of collective radiations are strongly dependent on the phase between two atoms. In the case of in-phase radiations, the frequency range to realize the three-photon blockade can be broadened as the control field increases. However, in the regime of the three-photon blockade, the property of collective radiations changes fro","authors_text":"Chengjie Zhu, Jingping Xu, Yaping Yang, Yufeng Han","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-09-26T07:01:47Z","title":"Electromagnetic control of the collective radiations with three-photon blockade"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.09826","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:faeca6e3af1c8a8bd7501f58c3afee7e2b72cff5ae0dd48a9abae2ddae66a0ce","target":"record","created_at":"2026-05-18T00:04:43Z","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":"ebdcef4a7d4dde3c6f896b6bdba8a79b6c4b109272f3ec8357f1ec7d5cb3c7e2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-09-26T07:01:47Z","title_canon_sha256":"6ab5d09283b0fcaf6be0043bb9886e412fc252be4619932d60b4328d4fb4e5fa"},"schema_version":"1.0","source":{"id":"1809.09826","kind":"arxiv","version":1}},"canonical_sha256":"4ba2ba7c1b1955dff61093e4ee70522f8239106dabc810cb72da265ce4b346ac","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4ba2ba7c1b1955dff61093e4ee70522f8239106dabc810cb72da265ce4b346ac","first_computed_at":"2026-05-18T00:04:43.554486Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:04:43.554486Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/3DWjpYgTM8XCPIYvCnpNjtyiJIo1ecPyfzpPyQ9ylzGuidAGxNpFZg2i3ulAwDpFzb+/t33MIwqqVu8aQ73CA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:04:43.554967Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.09826","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:faeca6e3af1c8a8bd7501f58c3afee7e2b72cff5ae0dd48a9abae2ddae66a0ce","sha256:cdd5523a3a4009a693a56a341425de9925b405923a28599dd8b2c5a37d07fa1a"],"state_sha256":"78326e0eec94525f5fe7a61a12957ef3440f7100443c7164f673ce7e9954fe5d"}
