摘　　要：介绍了用于可编程约瑟夫森结阵电压输出的平衡三进制算法和非整数进制算法的原理。通过1个实际可编程约瑟夫森结阵的案例,从算法的执行流程、时间复杂度、结数偏移量、区段选取情况等方面对这2种算法进行了全面的比较分析。发现非整数进制算法拥有更简洁的执行流程,更高的运算速度,可以选择更少子结阵输出相同的电压。而在绝对结数的偏移量方面,2种算法的结果几乎是一致的。另外,非整数进制算法既可以用于二进制和三进制序列表达整数计算,也可以用于非整数制序列整数表达计算,这种性质充分表明了其具有非常高的优越性。Introduces the principles of a balanced ternary algorithm and a non-integer multiple algorithm for the voltage output of programmable Josephson junction arrays.Through a comprehensive comparative analysis of these algorithms,including the algorithm's execution process,time complexity,structure number offset,and segment bias,based on a practical programmable Josephson junction array case,it is found that the non-integer multiple algorithm has a more concise execution process,higher computational speed,and the ability to choose fewer subarrays to output the same voltage.In terms of structure number offset,the results of the two algorithms are almost identical.In addition,the noninteger multiple algorithm can be used to expressing integer using binary sequence,ternary sequence or non-integer multiple sequence.It demonstrates that non-integer multiple algorithm has a strong advantage.
