While the mainstream of magnetometers based on NV centers uses so-called optically detected magnetic resonance, there has recently been a suggestion to use dispersive readout of a dielectric cavity to enhance the sensitivity of magnetometers. Here, we demonstrate that the dispersive readout approach can be significantly improved if a two-channel scheme is considered."},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Here, we demonstrate that the dispersive readout approach can be significantly improved if a two-channel scheme is considered.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That coupling the NV centers to two orthogonal cavity modes will yield a net sensitivity gain without introducing new decoherence, mode-cross-talk, or fabrication challenges that offset the benefit.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"A two-channel scheme with orthogonal modes in a dielectric cavity significantly improves dispersive readout sensitivity for NV-center magnetometers.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Two orthogonal modes of a dielectric cavity improve dispersive readout sensitivity for NV centers.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"465dac8be85007c26a9aabfddd4a3ee24a5d4084613a58912bcc853153296359"},"source":{"id":"2512.07356","kind":"arxiv","version":1},"verdict":{"id":"c95fd2fc-36ea-4afd-92a3-8fcfdaf92294","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-17T01:16:27.336752Z","strongest_claim":"Here, we demonstrate that the dispersive readout approach can be significantly improved if a two-channel scheme is considered.","one_line_summary":"A two-channel scheme with orthogonal modes in a dielectric cavity significantly improves dispersive readout sensitivity for NV-center magnetometers.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That coupling the NV centers to two orthogonal cavity modes will yield a net sensitivity gain without introducing new decoherence, mode-cross-talk, or fabrication challenges that offset the benefit.","pith_extraction_headline":"Two orthogonal modes of a dielectric cavity improve dispersive readout sensitivity for NV centers."},"references":{"count":14,"sample":[{"doi":"10.1103/physrevapplied.22.044069","year":2024,"title":"J.F.
