In this paper, we propose a different theoretical mechanism to achieve nonreciprocal macroscopic entanglement among magnons, photons, and phonons, based on magnon squeezing. Specifically, reversing the squeezing phase, namely theta -> theta + pi reverses the frequency shift and the effective dissipation rate simultaneously, producing two experimentally distinct configurations that enable nonreciprocal entanglement. Indeed, in contrast to conventional ap"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Reversing the squeezing phase, namely theta -> theta + pi, reverses the frequency shift and the effective dissipation rate simultaneously, producing two experimentally distinct configurations that enable nonreciprocal entanglement.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"Precise experimental control of both the amplitude and phase of the squeezed magnon mode is achievable while the system remains accurately described by the standard cavity-magnon-phonon Hamiltonian with added squeezing term.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"A theoretical scheme uses magnon squeezing phase reversal to achieve tunable nonreciprocal macroscopic entanglement in a magnon-photon-phonon hybrid system.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Reversing the squeezing phase of magnons produces two distinct configurations for nonreciprocal entanglement among magnons, photons, and phonons.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"9c6a06038ba097c04d6e424383372aa2b75004f0d353c7b92f05f0d841c12a6d"},"source":{"id":"2508.06850","kind":"arxiv","version":2},"verdict":{"id":"08f18d91-38ed-4f18-9a3a-487dd3d48fb9","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-19T00:28:00.637584Z","strongest_claim":"Reversing the squeezing phase, namely theta -> theta + pi, reverses the frequency shift and the effective dissipation rate simultaneously, producing two experimentally distinct configurations that enable nonreciprocal entanglement.","one_line_summary":"A theoretical scheme uses magnon squeezing phase reversal to achieve tunable nonreciprocal macroscopic entanglement in a magnon-photon-phonon hybrid system.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"Precise experimental control of both the amplitude and phase of the squeezed magnon mode is achievable while the system remains accurately described by the standard cavity-magnon-phonon Hamiltonian with added squeezing term.","pith_extraction_headline":"Reversing the squeezing phase of magnons produces two distinct configurations for nonreciprocal entanglement among magnons, photons, and phonons."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2508.06850/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":60,"sample":[{"doi":"","year":2024,"title":"Y., Qian, H., Ding, M","work_id":"14243193-90d4-4627-8641-edfcc4f1e750","ref_index":1,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2018,"title":"Li, J., Zhu, S.
