A quantum optical true random number generator based on splitting a beam of photons at a 50/50 beamsplitter has been demonstrated. A continuous stream of random numbers at a rate of 200 kbit/s can be generated. A mathematical method (Huffman coding a

A 1.1km long all-fiber quantum key distribution experimental setup has been realized for the first time at 850nm. The system employs the BB84 protocol to establish a secret key between two parties, the security of which is guaranteed by Heisenberg's

A pair of diffractive optical elements are desinged to implement the wavefront transformation from an elliptical-gaussian beam to a flat-top circular beam,with the aid of a new algorithm (SAIO) composed of a simulated annealing algorithm (SA) and an
