A 2022 experiment claimed this with a heavily simplified model, and critics argue that model is too small and too regular to support the claim.","posed_since":"2022","precise":"The protocol prepares two SYK systems in a thermofield-double state, inserts a qubit, applies a weak coupling of strength $\\mu$, and predicts a teleportation signal peaked near the scrambling time with operator size winding. Jafferis et al. (Nature 2022, doi:10.1038/s41586-022-05424-3) used a learned 7-qubit Hamiltonian; Kobrin, Schuster, Yao (arXiv:2302.07897) argued that it does not thermalize and matches SYK only for the training operators. Determine the minimal N and Hamiltonian class (dense or sparse SYK) for which the signal, its $\\mu$ dependence and size winding are distinguishable from generic small or commuting models. Answer: $N_{\\mathrm{min}}$ with explicit criteria, and whether present hardware reaches it.","problem_ref":null,"references":"","settled_by":"Numerics of the protocol at increasing N locating where gravitational signatures separate from generic ones, followed by an experiment at that N.","status_note":"Claimed in 2022 and disputed in a 2023 comment by Kobrin, Schuster and Yao.","title":"Minimal system size for verifiable traversable-wormhole teleportation","topic_ref":"3fefc56db1490dbc6700edd77c75843cae3c791bf1671e7876ab95cb15798bfa"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"2144fa88a7e977d12ba8bea2752c1ab6806724d729b97aa853b6671b57a30392","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"469c9b50d9882369d0040ff7bb0bc1b9be01fbad997e5a399b8e8f3a7f58e387","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"pTXgZ_UcVgGNWTXAb7sjzRLU1vbeQz4LwfjTAFHI-lsR3D5qlfiQXp0DRTRUA0wdWN1A_xFM8zlebryrPdIoAQ"},"schema":"pubphys.envelope/1"},"record_hash":"2144fa88a7e977d12ba8bea2752c1ab6806724d729b97aa853b6671b57a30392","leaf_index":1188}
