标题： SFQ counter-based precomputation for large-scale cryogenic VQE machines

摘要： 变分量子本征求解器（VQE）是量子计算带来实际益处的一个有前景的候选者。 然而，低温恒温器内外所需的带宽是扩展低温量子计算机的限制因素。 我们提出了一种带有单磁通量子电路的定制计数器模块，位于4K阶段，该模块预先计算了VQE计算的一部分并减少了跨温度通信的数量。 评估表明，我们的系统将所需的带宽减少了97%，并且在这种大幅减少的情况下，在一台具有10000个量子比特的机器上并行执行277个VQE程序时，总功耗减少了93%。 显示英文摘要

摘要： The variational quantum eigensolver (VQE) is a promising candidate that brings practical benefits from quantum computing. However, the required bandwidth in/out of a cryostat is a limiting factor to scale cryogenic quantum computers. We propose a tailored counter-based module with single flux quantum circuits in 4-K stage which precomputes a part of VQE calculation and reduces the amount of inter-temperature communication. The evaluation shows that our system reduces the required bandwidth by 97%, and with this drastic reduction, total power consumption is reduced by 93% in the case where 277 VQE programs are executed in parallel on a 10000-qubit machine.
