The question is whether a quantum bit can be stored the same way, with no active correction, in a material in our three-dimensional world.","title":"Self-correcting quantum memories at finite temperature","topic_ref":null,"why":"A passive quantum memory would remove much of the hardware and control cost of error correction and answers a basic question about thermal stability of quantum order."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"0ac91b5262bc7d232a08682ee033f23c99f87d6c0e1021af156138bac07de11f","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"4c8b9311e532f196b5093fd63fcd07ca21b89d72b76ba1787abe24c139d0f1e1","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"93k2-E-pjfKsnVFYY4sSIv61lcS-DlxQCSOsBuLbqwZyhMPlrjSDtvAZV5gk-2XBAyiYTjEtVfjjTytAOfxvCw"},"schema":"pubphys.envelope/1"},"record_hash":"0ac91b5262bc7d232a08682ee033f23c99f87d6c0e1021af156138bac07de11f","leaf_index":345}
