However, conventional measurements that rely on the electron energy loss spectrum (EELS) are inherently destructive to electron qubits, thereby constraining their applicability. In this Letter, we propose a scheme that performs projection measurement on the electron comb basis, where high measurement precision can be achieved with bright squeezed vacuum states and strong PINEM couplin","authors_text":"Feng-xiao Sun, Qiongyi He, Yunquan Liu, Zihang Zou","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-08-11T11:59:13Z","title":"Projection measurement of the comb basis through free-electron-photon interactions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2608.10831","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":"sha256:67a3e93b9cad2b42fb18f7e45f300d981960db214034af0836ddddc98c3f197a","target":"record","created_at":"2026-08-12T01:23:24Z","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":"e74bda5178b32a8d9537cda0f7c8b1cdb40f2758c822223967d0f7b6aac2c492","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-08-11T11:59:13Z","title_canon_sha256":"0ae14814104b16995ee3bc49c7402efd3a52651dbee515154c407601ebe219dc"},"schema_version":"1.0","source":{"id":"2608.10831","kind":"arxiv","version":1}},"canonical_sha256":"e03e9c22f3d35b529053ff15c6b807ef203877e0ac89d55bd9cd579027e2872a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e03e9c22f3d35b529053ff15c6b807ef203877e0ac89d55bd9cd579027e2872a","first_computed_at":"2026-08-12T01:23:24.026182Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-12T01:23:24.026182Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jlUSOdO0uW+hWGKT0vokY5i49E+kAr/N3ZKWoophXISD/RVDaPMD//Y2uAAMCHJB3uNJiK+8KhDKg6tKJBHUBA==","signature_status":"signed_v1","signed_at":"2026-08-12T01:23:24.027831Z","signed_message":"canonical_sha256_bytes"},"source_id":"2608.10831","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:67a3e93b9cad2b42fb18f7e45f300d981960db214034af0836ddddc98c3f197a","sha256:c54e16ac2d05e93e95f8bca3f14cd9b5cbcbde4462a5b52809f5ff13601bc0cd"],"state_sha256":"9ddb1d82c25547eb3f698c4f3cdea92025b22a06962bbedf9facd0423cf0786d"}
