超导量子计算机具有芯片加工技术成熟、系统集成度高、可扩展性能好等优势,但超导量子计算需要加大芯片的量子位集成度,同时需保证量子芯片的退相干时间来实现容错量子计算。对超导量子芯片的前沿进展进行分析,阐述超导量子比特的物理机理与优缺点,并研究几种最基本的量子比特特点。讨论超导量子比特之间的耦合方案,包含局域耦合和非局域耦合。通过对近年来主流扩展和布局方案进行分析,结果表明,实现量子算法编程适用一维或者二维阵列,而最大纠缠和全耦合则选用环绕式的扩展方案,可为大规模、高效率的量子计算的芯片设计提供一种思路。 |

Superconducting quantum computers have the advantages of mature chip processing technology,high system integration, and good scalability. However, superconducting quantum computing needs to increase the quantum integration of chips and ensure decoherence time of quantum chips to achieve fault-tolerant quantum computing. The advancement of superconducting quantum chips is analyzed, and the physical mechanism, advantages and disadvantages of superconducting quantum bus are presented,and several basic quantum bits characteristics are studied. The coupling scheme is discussed between superconducting qubits,including local and non-local coupling. Analysis results on mainstream expansion and layout schemes in recent years show that quantum algorithm programming is suitable for one-dimensional or two-dimensional arrays,while maximum entanglement and full coupling use wraparound expansion schemes to achieve large-scale,highefficiency quantum to provied an idea for the design of the computational chip. |
