Chinese scientists create world’s coldest alloy. It may surprise DARPA
AI Summary
Chinese scientists have created a novel rare earth alloy capable of achieving extremely low temperatures, potentially replacing helium-3 in cooling applications. The alloy, developed by researchers at the Chinese Academy of Sciences, has been used to build a mini-fridge that reaches temperatures near absolute zero without moving parts. This development coincides with a recent call from DARPA for helium-3-free cooling systems for quantum and defense technologies. The Chinese team published their findings in Nature less than two weeks after DARPA's announcement. The alloy offers a potentially mass-producible and portable cooling solution for quantum computing and space exploration, providing a self-reliant alternative to existing methods.
