A rare earth ‘China solution’ that leaves US defence agency in the cold
‘China solution’ delivers helium‑3‑free cooling tech for quantum chips, offers stable, portable system to support space exploration.
Chinese researchers have unveiled a new rare earth alloy so cold and efficient it could upend decades of reliance on helium-3 and send shock waves through the global race for quantum computers or ultra-sensitive detectors.
A mini-fridge built with the alloy has achieved temperatures extremely close to absolute zero using no moving parts. And it comes at a time when the US Defence Advanced Research Projects Agency (DARPA) is actively hunting for exactly such a technology.
