Following the lead of China, the European Union (EU), and South Korea, Japan has unveiled plans to build its own long-distance quantum communication network. The first phase will link the country’s three major cities—Tokyo, Nagoya, and Osaka—covering a distance of 600 kilometers. Construction is expected to be completed by early 2027, with field testing planned later that year. The initial rollout will focus on sectors where confidentiality is critical, such as healthcare and finance, to establish a Japan-specific quantum communication standard by 2030.
Rapidus plans to begin construction on a second fabrication plant in Chitose, Hokkaido, in fiscal 2027 to produce 1.4nm and eventually 1nm chips, according to reports from Nikkei and Yomiuri Shimbun. The move underscores Japan’s push to return to the front of advanced logic manufacturing, even as Rapidus works to complete its 2nm process and secure the funding required to sustain its roadmap. However, the company has since denied this reported timeline.
Google’s expanding Tensor Processing Unit (TPU) strategy is emerging as a serious challenge to Nvidia’s long-running dominance in AI accelerators, particularly after a report from The Information revealed that Meta is in talks to begin using Google TPUs in its data centers in 2027 under a potential multibillion-dollar agreement.
