Time evolution of negative binomial optical field in a diffusion channel
《Chinese Physics B》2015年第9期97-100,共4页刘堂昆 吴盼盼 单传家 刘继兵 范洪义 
Project supported by the National Basic Research Program of China(Grant No.2012CB922103);the National Natural Science Foundation of China(Grant Nos.11175113,11274104,and 11404108);the Natural Science Foundation of Hubei Province,China(Grant No.2011CDA021)
We find the time evolution law of a negative binomial optical field in a diffusion channel. We reveal that by adjusting the diffusion parameter, the photon number can be controlled. Therefore, the diffusion process ca...

Mocking up a Dephasing Channel with a Minimal-Sized Environment
《Chinese Physics Letters》2012年第8期25-28,共4页WU Zhen 
Supported by the National Natural Science Foundation of China under Grant No 10974225;the National Basic Research Program of China under Grant No 2012CB922102.
In order to model the most general quantum operation on a d-dimensional system,a d^(2)-dimensional environment is usually needed.We focus on the quantum dephasing process and find that this channel can be modeled by a...
