As the measurement rate rises, the system switches sharply from highly entangled to weakly entangled, a phase transition visible only in the record of individual measurement outcomes.","title":"Measurement-induced entanglement transitions in monitored circuits","topic_ref":null,"why":"It is a new type of phase transition in quantum dynamics and is linked to how well quantum information can be protected and learned."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"da5948613fb7c747a01db9b5effa765ea41c69dc5d5e33ffbeb4df2a77c0fb36","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"bd92ea7fbbc1a0554674d82f59d46e3e39b63f0daf499ebbd6ba4ddfe6040848","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"p8rJTXEAUU4mueJCa6YJ351DAUj6mTssjmTCe4yk2wHrxHgGNpnArayNVzCXK0odMxDhIgHwd3g-c1TDNKxnCw"},"schema":"pubphys.envelope/1"},"record_hash":"da5948613fb7c747a01db9b5effa765ea41c69dc5d5e33ffbeb4df2a77c0fb36","leaf_index":338}
