By using two-tone spectroscopy, the energies of the six lowest levels of each circuit are determined. We find huge Lamb shifts that exceed 90% of the bare qubit frequencies and inversions of the qubits' ground and excited states when there are a finite number of photons in the oscillator. Our experimental results agree with theoretical predictions based on the quantum Rabi model.","authors_text":"Fumiki Yoshihara, Kazuki Koshino, Kosuke Kakuyanagi, Kouichi Semba, Sahel Ashhab, Shiro Saito, Takao Aoki, Tomoko Fuse, Ziqiao Ao","cross_cats":["cond-mat.supr-con"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-12-13T23:11:25Z","title":"Inversion of Qubit Energy Levels in Qubit-Oscillator Circuits in the Deep-Strong-Coupling Regime"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.05039","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":"sha256:224d551e7a4a5b5d7c744f95a159b5010e5ea25d276fa087008468f33647f49a","target":"record","created_at":"2026-05-18T00:16:29Z","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":"5a73174afc842d3480adea8ba7e62bc62e7d89d73067db8134b575a5a7fff0aa","cross_cats_sorted":["cond-mat.supr-con"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-12-13T23:11:25Z","title_canon_sha256":"65bfcaba78a26a4869b04c94679a46a2baa4c60958d37f8cbd40ff0c1c2807f7"},"schema_version":"1.0","source":{"id":"1712.05039","kind":"arxiv","version":2}},"canonical_sha256":"f2234529cff8f6cb29d21278f8f530ceb4e6b527da64a964907f3554f2fb7de2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f2234529cff8f6cb29d21278f8f530ceb4e6b527da64a964907f3554f2fb7de2","first_computed_at":"2026-05-18T00:16:29.789537Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:16:29.789537Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lWAWZfJkaiQW7Ucdc6DlmoxTlCr1ul+TASshp11Uu5jJTM2DTQqa8WpeU44Z6knF/Fp47Y65bV7wgAbkMZoxBw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:16:29.790086Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.05039","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:224d551e7a4a5b5d7c744f95a159b5010e5ea25d276fa087008468f33647f49a","sha256:084e3d0aa97c7ac50bb3dd17d455f166ecdaefaf6d0378cd623b49105c607860"],"state_sha256":"a56ef21656f1a60a24c47cfcc3508c583c1125c8948a35461dd0530d72f54a2b"}
