Jian-Wei Pan, Professor at the University of Science and Technology of China, in Hefei, is the winner of the prestigious Zeiss Research Award 2020. He is one of the world's leading researchers in the field of quantum technology.
One of the most remarkable results of Jian-Wei Pan's research is the distribution of entangled photons over a distance of 1200km, by far the longest distance ever reached. He achieved this using a light source that is installed on a satellite and emits entangled photons. Entangled photons can be used in conjunction with quantum cryptography to enable two parties to exchange a secret key.
If a secret key is exchanged, it can be used to encrypt an email or secure a bank transfer.
