计算能耗高和散热问题使传统计算芯片的集成度和运算能力的提升遇到瓶颈.大规模量子计算探索的关键是比特的相干叠加性和可逆性.因此,可逆计算既作为一种可能从根本上解决计算耗能高和散热问题的方案,又作为一种兼容量子计算的方案,近年来在理论上和实验上得到了深入的研究.本文介绍了可逆计算的基本原理,总结了目前基于微机械、传统微电子和超导领域的可逆计算实验研究进展,分析了超导器件实现可逆计算的独特优势,并着重对其中两种器件的工作原理进行了论述.
Computation of high energy consumption and cooling problems make the traditional computing chip integration and computing power to enhance the bottleneck.The key to large-scale quantum computing exploration is the coherence and bit reversibility of the bit.Therefore, reversible computing is not only as a possible And solve the problem of high energy dissipation and heat dissipation as a fundamental solution, and as a scheme compatible with quantum computing, it has been studied theoretically and experimentally in recent years.In this paper, the basic principle of reversible calculation is introduced, The research progress of reversible calculation in micromechanics, traditional microelectronics and superconductivity fields is analyzed. The unique advantage of reversible calculation of superconducting devices is analyzed. The working principle of two devices is emphatically discussed.
