China’s ambitions are reflected in people like Pan Jianwei, the leading researcher for its quantum satellite.

Quantum communications involves phenomena so far outside our traditional understanding of the universe that Albert Einstein called it “spooky.” It posits the existence of particles that can instantaneously “teleport” information to one another, seemingly in defiance of space and time.

In 2014, Mr. Pan’s team made two infinitesimally small bits of information disappear and then reappear elsewhere—a primitive version of Star Trek-style teleportation that marked the world’s most advanced effort to date. The results of the experiment were published in Nature, a prestigious peer-reviewed scientific journal. The work has other applications, making unbreakable codes and super-powerful computers.

All of that was far off for Mr. Pan in the 1990s. Looking at the state of Chinese research, he says he had no choice but to head overseas, securing a fellowship at the University of Vienna. His English was so poor that on his first day he mistakenly went to his landlord instead of the university fellowship office to request his stipend.

“I couldn’t bear the food, but I found that salami was palatable if you soaked it in oolong tea,” Mr. Pan says.

Pan Jianwei, a Chinese quantum physicist, is leading research into teleportation at the University of Science and Technology of China in Shanghai. Pan Jianwei, a Chinese quantum physicist, is leading research into teleportation at the University of Science and Technology of China in Shanghai.

He got in on the ground floor of quantum teleportation. Chinese physics lagged behind so much that Mr. Pan didn’t know the field existed, and he remembers proudly outlining the idea to Vienna colleagues only to be met with pained silence. He thought he invented the idea; they were already working on it.
