DW's investigative team and the German investigative newsroom CORRECTIV have delved into the history of a remarkable scientific partnership that has spanned two decades. This partnership revolves around the fascinating field of quantum physics, which has the potential to impact human rights and alter the balance of power between China and the US. At the center of this collaboration is the venerable Heidelberg University, along with its honorary professor Pan Jian-Wei, who was recognized as one of the world's 100 most influential people by the renowned US news magazine, Time, in 2018. Since 2003, there has been a continuous exchange of knowledge between Germany's oldest university and Professor Pan in the field of quantum research. However, experts have cautioned about the potential military applications of quantum technology. Our research has led us deep into the realm where academic freedom collides with national security interests.
