We focus on the case where the light-matter interaction is enhanced by a cavity. We show that the optimal write process (maximizing the storage efficiency) is related to the optimal read process by a reversal of the {\\it effective time} $\\tau=\\int dt g^2(t)/\\kappa$, where $g(t)$ is the time-dependent coupling and $\\kappa$ is the cavity decay rate. We discuss the implementation of the protocol in a rare-earth ion doped crystal, where an optical transition can be turned on and of","authors_text":"Adam Green, Arnaud Rispe, Christoph Simon, Erhan Saglamyurek, Khabat Heshami, Neil Sinclair, Wolfgang Tittel, Yang Han","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2011-06-17T15:20:19Z","title":"Controllable-dipole quantum memory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1106.3513","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:e35e205aa1df89197ade66c010a7dd8117cab67bc4b031ad80192ed06cedb47e","target":"record","created_at":"2026-05-18T02:01:35Z","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":"ee499d667b3d7b630b5baf0e0861114f94e44a9ed857916dea48b983e777d0e0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2011-06-17T15:20:19Z","title_canon_sha256":"57c80904028eabb08def0354041d1a4843e70f6437c53b92e0dbbb6153ec601b"},"schema_version":"1.0","source":{"id":"1106.3513","kind":"arxiv","version":2}},"canonical_sha256":"4b76cbf3377448f819d87e0472fb8ab7a2a49dffa12e80278b089fabed56f613","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4b76cbf3377448f819d87e0472fb8ab7a2a49dffa12e80278b089fabed56f613","first_computed_at":"2026-05-18T02:01:35.613024Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:01:35.613024Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rmohicMyB2DUNOgAnLpQlsGO9WbWGqz6nsexq+vXm73qXXQWAx+KuTYcCc8RZVgYpgKbxWr7/Px7kfbYmCWzDg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:01:35.613805Z","signed_message":"canonical_sha256_bytes"},"source_id":"1106.3513","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e35e205aa1df89197ade66c010a7dd8117cab67bc4b031ad80192ed06cedb47e","sha256:34a967b2ca43721325086c8b702215bda5a1e1d4ca5ac2d998619eeed2c7a72e"],"state_sha256":"ebe5757cc1d9052150a6b7be262e1da20e7c12c3ba975b99b27149382d91d68e"}
