Having fun with science

Star scientist Pan Jianwei finds not only purpose but also peace and happiness, exploring the mind-twisting mysteries of quantum physics. Yu Fei and Xu Haitao report.

Albert Einstein may have thought quantum entanglement kind of "spooky", but the world's first quantum satellite, launched by China last year, has proved that the phenomenon of particles remaining connected so that actions performed on one affect the others, still exists at a distance of over 1,200 kilometers.

And Pan Jianwei, the satellite's lead scientist, now has a bigger goal: to test quantum entanglement between the Earth and the moon at a distance over 300,000 kilometers.
