Quantum cryptography: from “unbreakable codes” to “quantum hackers”
Abstract: Quantum key distribution (QKD) protocols have been proven to be information theoretically secure based on fundamental laws in quantum mechanics. However, practical QKD systems often deviate...

Experimental Investigation on Quantum Information via Free-space Optical Channel
Abstract: Generally speaking, there are mainly two types of quantum channels, fiber links and free-space links. Considering absorptive losses in the channel and dark counts in the detection, the dist...

An introduction to quantum mechanism design
Abstract: Quantum strategies have been successfully applied to game theory for years. However, as a reverse problem of game theory, the theory of mechanism design is ignored by physicists. In my talk...
