Construction of Minimum Bandwidth Regenerating Codes with Combinatorial Design被引量：1
《Wuhan University Journal of Natural Sciences》2016年第3期229-234,共6页CAI Feng GUO Wangmei 
Supported by the National Natural Science Foundation of China(61271174,61301178)
We study the construction of minimum bandwidth regenerating code with combinatorial design. At first, a method of constructing minimum storage regenerating （MBR） codes is presented, which can tolerate only one-node ...

A Method of Estimating the Eigenstates of Density Operator
《Wuhan University Journal of Natural Sciences》2015年第5期386-390,共5页GAO Jingliang 
Supported by the National Natural Science Foundation of China(61271174,61372076,61301178)
We describe a mathematical structure which corresponds to the eigenstates of a density operator. For an unknown density operator, we propose an estimating procedure which uses successive ＂yes/no＂ measurements to sca...
