一维量子点阵列自旋链上多比特态的信息传输

利用演化算符作泰勒展开,作用于初态的信息上;使用湮灭算符和其所产生的算符,作用在单比特态上,使一维量子点阵列自旋链上的多比特态量子信息实现完美传输;通过计算初态演化到末态的概率幅,使保真度达到1时实现信息完美传输.结果表明:当相邻量子点之间的交换相互作用和自旋链长度都相同时,保真度传输的比特数越大,传输时间越短.

The relationship between the ratio of second fingers to fourth fingers （2D：4D） and the inheritance of athletic ability

This paper summarizes the ratio of 2D and 4D to the inheritance of athletic ability： 2D： 4D has been stereotypes before birth, and the mother＇s uterus testosterone concentration there is a negative correlation between the relationship, Testosterone concentration affects the development of the right hemisphere and spatial visual ability of the brain, thus affecting athletic ability. The mitochondrial genome （mtDNA） polymorphism is directly related to motor activity and has a high maternal genetic trait. Athlete mothers have higher testosterone, and their children have athletic advantages. 2D： 4D and mtDNA have good genetic markers, which are of great significance and prospect for the study of their inheritance of motor ability.

Multiple Multi-Qubit Quantum States Sharing

A multiple multi-qubit quantum states sharing scheme is proposed,in which the dealer can share multiple multi-qubit quantum states among the participants through only one distribution and one recovery.The dealer encodes the secret quantum states into a special entangled state,and then distributes the particles of the entangled state to the participants.The participants perform the single-particle measurements on their particles,and can cooperate to recover the multiple multi-qubit quantum states.Compared to the existing schemes,our scheme is more efficient and more flexible in practice.
