Galaxy Research Director Comments on Google Quantum Paper: Practical Engineering Challenges such as Error Correction Still Unsolved BlockBeats news, on March 31st, Galaxy research director Alex Thorn posted on the X platform, stating that "this Google quantum paper is very important because researchers have made breakthroughs in circuit optimization. Compared to the previous solution that required about 9 million physical qubits (Litinski 2023, based on photon architecture), the circuit constructed in this study is expected to run Shor algorithm on about 500000 physical qubits under reasonable circumstances, and is based on a superconducting architecture that is consistent with its own processor parameters. This means that the circuit design has achieved an optimization improvement of about 20 times, which is partly due to better circuit design and partly due to hardware assumptions that are closer to reality. However, the actual engineering challenges such as error correction, decoherence, and gate fidelity have not changed. In addition, they developed these circuit designs but did not disclose specific details. Instead, they used a "responsible disclosure" method (using zero knowledge proofs, ZKP) to prove the existence of these circuits, allowing the outside world to verify their conclusions without seeing the specific designs. This approach is innovative while avoiding the leakage of critical designs. As for whether the engineering level can achieve the required error correction capability, control decoherence, and achieve sufficient gate fidelity in the future, it is still an independent and unresolved issue
