This is a special issue (Part II) expanding on a previous special issue [1] dedicated to future computing technologies. Part I appeared in the January 2019 issue of the PROCEEDINGS OF THE IEEE. Part II was inspired by our desire to highlight technological prospects for continued advances in computing despite diminishing returns from traditional investments aimed at increasing the device density and clock frequency in digital circuits. In our preface to Part I, we noted that the future of computing is at a crossroads—a statement still valid today.

非硅、非冯诺依曼计算——第二部分

这是一期特刊（第 II 部分），是对之前专门讨论未来计算技术的特刊 [1] 的扩展。第 I 部分发表于 2019 年 1 月的 PROCEEDINGS OF THE IEEE。尽管旨在增加数字电路中的设备密度和时钟频率的传统投资的回报正在减少，但我们希望强调计算持续进步的技术前景，这激发了第二部分的灵感。在第一部分的序言中，我们指出计算的未来正处于十字路口——这一声明今天仍然有效。
