There are no secure public-key quantum money schemes in the literature; as we show in this paper, the only previously published scheme [1] is insecure. We introduce a category of quantum money protocols which we call collision-free. For these protocols, even the bank cannot prepare multiple identical-looking pieces of quantum money. We present a blueprint for how such a protocol might work as well as a concrete example wh","authors_text":"Andrew Lutomirski, Avinatan Hassidim, David Gosset, Edward Farhi, Jonathan Kelner, Peter Shor, Scott Aaronson","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2009-12-21T04:39:26Z","title":"Breaking and making quantum money: toward a new quantum cryptographic protocol"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0912.3825","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":"sha256:5a52909950dc01a881e3b8830ccd091cc3fbcdcbd4032169644b44de1acecff7","target":"record","created_at":"2026-05-18T04:23:34Z","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":"7061f810080bca5210327136213fdce646aa6e1a8d63a5e14e219b2e9775654f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2009-12-21T04:39:26Z","title_canon_sha256":"7948005a581b3d83e37d030c1069b7965820cb7728c65fde1d0290ebc8fce741"},"schema_version":"1.0","source":{"id":"0912.3825","kind":"arxiv","version":1}},"canonical_sha256":"2e6d7f0e41c4e3e97b4e56365298fe88aed9f61f8f5c9e9e54db12f9b9c33fed","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2e6d7f0e41c4e3e97b4e56365298fe88aed9f61f8f5c9e9e54db12f9b9c33fed","first_computed_at":"2026-05-18T04:23:34.359562Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:23:34.359562Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/mEz8kPgdSR7mBO3zhKJAdwsNnTeE7+ouKoppWJPp3Nors55GOuShlRWnQNGB8uUMJ/pxV58GzQOiNs4RfAmDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:23:34.360086Z","signed_message":"canonical_sha256_bytes"},"source_id":"0912.3825","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5a52909950dc01a881e3b8830ccd091cc3fbcdcbd4032169644b44de1acecff7","sha256:f7b30728ed3f501a3c2038fe363b1ebb5f75e9b35511fcc94c91bd1d26c0a6f8"],"state_sha256":"e78f02294ce6e5304a64c57fd23108c8d58570a422e9bcea88a458c3ce3521bf"}
