自作PCでの選び方・注意点

Amazon AWS Ocelot は「Quantum Error Correction Research (Cat qubit Hardware-level intrinsic error protection新Approach)」「AWS Customer (Existing AWS infrastructure access・AWS Braket via integration)」「Strategic Government / Academic Quantum Computing Research」用途のResearch-grade Quantum Computing Chip。Consumer / 自作PC範囲外・Operating Temperature 10-20 mK Dilution refrigerator必須・AWS Caltech Research grade Custom Manufacturing で AWS Strategic Customer access only (2026年Q1-Q2 AWS Braket platform integrate予想)。Cat qubit Approach (1985年理論発表のSchrödinger's Cat-based Quantum Computing) は IBM / Google Superconducting Transmon (現Industry dominant) と全く異なる Quantum Computing Future Approach + Microsoft Majorana 1 (Topological qubit) と類似 Hardware-level intrinsic error correction focus・両者2024-2025年 Quantum Computing Industry vendor Watershed Moment (Hyperscaler Top 2 Hardware-level error correction Approach demonstration) でSuperconducting Transmon dominant approach 将来 disruption potential示唆。AWS Braket platform integration 2026年Q1-Q2 → Customer access timing で Pre-Investment value評価必要・5 logical qubits initial demonstration scale で実用 Quantum algorithm (Shor / Grover等) には不足 + Cat qubit Scale up to 30-50+ logical qubits 2027-2030年予定。
