Using them needs links between distant qubits, fast decoding and a way to compute on the stored qubits.","title":"Quantum LDPC codes and their hardware realization","topic_ref":null,"why":"They could cut the qubit cost of fault-tolerant quantum computing by an order of magnitude or more."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"71196b612de8cb112565b0581c5d9a20e4fcd90e9f372725435ebd01a1125190","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"be5bd6be5cf69e06892657751109ecec6d656e8ee09c061ed7ed2e9cb6b8d91a","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"ocz3xTft6b534y_u2HN0Re0qbqBlxOtFX5r7UGjNI1rc6o-foIEXvdyjpr6mq7_A7zEo11e12uLDAoTLakxaCw"},"schema":"pubphys.envelope/1"},"record_hash":"71196b612de8cb112565b0581c5d9a20e4fcd90e9f372725435ebd01a1125190","leaf_index":339}
