New radiation-proof quantum state could unlock deep space travel

Researchers at the University of California, Irvine have discovered a new quantum phase of matter within a custom-synthesized material called hafnium pentatelluride. By subjecting this material to ultra-high magnetic fields of up to 70 Teslas—about 700 times stronger than a typical fridge magnet—at Los Alamos National Laboratory, the team observed a sudden loss of electrical conductivity, signaling a transition into this exotic state. This phase involves electrons pairing with positively charged holes to form a tightly-bound fluid of excitons that spin in unison, potentially enabling signals to be carried by spin rather than electrical charge. This discovery opens avenues for energy-efficient spin-based electronics and quantum devices. A key advantage of this new quantum state is its resistance to radiation, which could make it ideal for electronics used in deep-space missions where conventional semiconductors fail due to harsh radiation environments. The material’s robustness could lead to self-charging, radiation-proof computers and devices capable of long-term operation in space, addressing
