Qubus Quantum Computer

研究了基于相干光脉冲和固态量子比特的容错量子计算机的体系结构和系统组成技术。我们提出了具有拓扑表面编码的分层架构，并表明物理量子比特的总数为10^8-10^9，计算时间为1-10天，可以进行有意义的计算。我们还开发了相干光脉冲控制自旋量子比特和可变隧道能量约瑟夫森结通量量子比特技术。

Architectures and system constituent technologies for fault-tolerant quantum computers based on coherent optical pulses and solid state qubits are studied. We proposed the layered architecture with topological surface codes and showed the total number of physical qubits of 10^8-10^9 and computational time of 1-10 days are needed to perform meaningful computations. We also developed the coherent optical pulse controlled spin qubit and variable tunnel energy Josephson junction flux qubit technologies.
