Voltage-controlled adiabatic transitions between the qubit operations and readout conditions allow high-fidelity mapping of quantum states. We show that a large ratio both in relaxation time vs. tunneling time (~ 50) and singlet-triplet splitting vs. thermal energy (~ 20) allow energy-selective tunneling-based spin-to-charge conversion with readout visibility ~ 92.6%. Combined with ac driving, we demonstrate high visibility coherent Rabi and Ramsey oscillatio","authors_text":"Byoungwoo Kang, Dohun Kim, Gyeonghun Kim, Hwanchul Jung, Hyeongyu Jang, Jaemin Park, Jehyun Kim, Min-Kyun Cho, Vladimir Umansky, Wonjin Jang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2021-01-28T08:27:00Z","title":"Single-shot readout of a driven hybrid qubit in a GaAs double quantum dot"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2101.11864","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":"sha256:2e207b730011af2aafb54cbdd0e26f00c36b613767c5d35928c9d5e4c9045ea7","target":"record","created_at":"2026-07-05T02:52:27Z","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":"e2b524b860a3635b2d1a68946a42c664db9a423eff53f2bec0ded153d545cdce","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2021-01-28T08:27:00Z","title_canon_sha256":"0505021569178206faf1386f728399a824131cb6be943e10e241781badae8e18"},"schema_version":"1.0","source":{"id":"2101.11864","kind":"arxiv","version":2}},"canonical_sha256":"103a376e6a25447b463a6720763c2fe512e8ca8d8c87a3fd3180a1f0c79a5df5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"103a376e6a25447b463a6720763c2fe512e8ca8d8c87a3fd3180a1f0c79a5df5","first_computed_at":"2026-07-05T02:52:27.731793Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:52:27.731793Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rLyk6cm+3SZXFVGq4RAgIcQoV5fR6a/yntuKV38FP3GdWkP1LNY43ZhKEy/ZJszsPNuyOGOq2zX39Pe4tMhPBA==","signature_status":"signed_v1","signed_at":"2026-07-05T02:52:27.732274Z","signed_message":"canonical_sha256_bytes"},"source_id":"2101.11864","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2e207b730011af2aafb54cbdd0e26f00c36b613767c5d35928c9d5e4c9045ea7","sha256:384d3e0487d7dbbdf4995d81a5766f3869ec5b726bbd6d1025163bf3407aa2df"],"state_sha256":"aa179a18b12028e028dcb15ff10f1b07ace4e95477227a17455cd3caa620c3d9"}
