LDA is a popular feature extraction technique for face recognition. However, it often suffers from the small sample size problem when dealing with the high dimensional face data. Fisherface and Null Space LDA (N-LDA) are two conventional approaches to address this problem. But in many cases, thes.....

This technology takes advantage of a principle in quantum optics to generate truly random numbers, which is completely different from conventional random number generators that only can create psuedorandom numbers. As is known, randomness is the intrinsic property of quantum physics. For many appl.....

Quantum key distribution over networks is a long-standing problem for practical applications. In this research, we solve this problem over current and next generation optical fiber communications networks---wavelength division multiplexing (WDM) fiber links with conventional optical communication c.....
