Chinese scientists have prepared the coldest man-made material known so far on the space station. The accumulation of cold atom research and system engineering that supports this achievement also provides an important foundation for research and development of quantum computation of neutral atoms. According to a November 6 report, the Chinese research team used the ultra-cold atomic physics test cabinet of the space station's Mengtian test module to reduce the equivalent temperature of the rubidium atomic cloud to 9.7 pikelvin through all-optical trap cooling technology, and achieved continuous observation for up to 7 seconds. The relevant results were published in “Science”.
