Nuclear-spin swap extends room-temperature entanglement lifetime up to 240-fold

AI Summary

Chinese scientists have achieved a significant extension — up to 240-fold — of room-temperature entanglement lifetime in a solid-state system by transferring entangled states from electron spins to nuclear spins. The breakthrough may advance quantum technology development.

Researchers in China have extended the lifetime of entanglement in a room-temperature, solid-state system by up to a factor of 240. Led by Shuo Ren and Rui-Jian Liang at the University of Science and Technology of China in Hefei, the team transferred entangled states from the electron spins of solid-state defects to the spins of surrounding atomic nuclei, which are far more resilient to noise. The research has been published in Physical Review Letters.
