We propose a scalable scheme for creating features narrower than classically achievable, with reduced use of quantum resources and consequently enhanced resistance to loss. The scheme is an implementation of interferometric lithography using a mixture of an SPDC entangled state with intense classical coherent light. We measure coincidences of up to four photons mimicking multiphoton absorption. The results show a narrowing of the interference fringes of up to 30% with respec","authors_text":"Itai Afek, Oron Ambar, Shamir Rosen, Yaron Silberberg, Yonatan Israel","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-01-03T14:04:28Z","title":"Sub-Rayleigh lithography using high flux loss-resistant entangled states of light"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1201.0637","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":"sha256:41e762e004387d02eb0d69d606988cfbffef9b6063b7826bf51de5996a8b98d6","target":"record","created_at":"2026-05-18T03:22:53Z","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":"5ef58c483260ac054a8b58e01eb0552763a99e467a30a6eacbceedfdcbef4352","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-01-03T14:04:28Z","title_canon_sha256":"301da3f5ffe830b8ef8379527fe924f40d997cf8cfbf6e6d35021d3b88ddec31"},"schema_version":"1.0","source":{"id":"1201.0637","kind":"arxiv","version":1}},"canonical_sha256":"b6c7628a8773af1ee5ee79200cf95b811ecfd51760da5b46104d87a9a6ac3c6f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b6c7628a8773af1ee5ee79200cf95b811ecfd51760da5b46104d87a9a6ac3c6f","first_computed_at":"2026-05-18T03:22:53.491214Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:22:53.491214Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xtB+/J4TBYTXyki0gxszu2wd91DoKfbIrwyp8S6fHgS1mzAMuX1mgZp/fGnE4V+ekMfWhiPx5Rz2YUAYS7lnAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:22:53.491717Z","signed_message":"canonical_sha256_bytes"},"source_id":"1201.0637","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:41e762e004387d02eb0d69d606988cfbffef9b6063b7826bf51de5996a8b98d6","sha256:664dcda20ddc1741c881b7f54cb54c62e7bfa3cbde5618dbb22847ec1aeb06e4"],"state_sha256":"26ad3069870efea56f89583e27da3f8136a7fd3cc03efd7ec5aba3ff5d705f6c"}
