In a quantum spin glass a sideways magnetic field adds quantum fluctuations, and how the system freezes as that field is lowered decides how well quantum annealing machines can find low-energy states.","title":"Quantum spin glasses and quantum annealing","topic_ref":null,"why":"The freezing transition of quantum spin glasses sets the speed limit of quantum annealers and is the reference case for quantum phase transitions with strong disorder."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"6a06d9efe63e0d5c899a305b177222954e51aee2bd4e5e8b45a9050de1c8e89c","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"7fde93a2ab0eb39c0738f7a8452422b96820b90de746f8b71644fc3daff87437","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"pVTcokXUG-w8HlbYvqn_U4Rgc6xc5nYu2CduBGmrckj-bJJeVBwSuaF8kmkJSTYiHPzU4TxTanaP-j__egLkCQ"},"schema":"pubphys.envelope/1"},"record_hash":"6a06d9efe63e0d5c899a305b177222954e51aee2bd4e5e8b45a9050de1c8e89c","leaf_index":164}
