AI Summary

Researchers at the University of Science and Technology of China in Hefei have increased the duration of entanglement in a room‑temperature solid‑state system by as much as 240 times. Led by Shuo Ren and Rui‑Jian Liang, the team moved entangled states from electron spins in solid‑state defects to the spins of nearby atomic nuclei, which are far less susceptible to environmental noise. The work demonstrates that nuclear spins can serve as more durable carriers of quantum information in ambient conditions. The findings were reported in Physical Review Letters.
