三格点自旋链上单比特信息传输的精确调控
Precise control about single-bit information transfer in the spin chain with 3 lattice points
摘要
Abstract
The analytical solution method is introduced to study the perfect transfer of single-bit quantum information in a spin chain with a lattice number of 3.After applying a magnetic field that varies gradually between lattice points to the spin chain,an accurate solution is given for the influence of this magnetic field on the perfect transfer of single-bit information.Further analysis concludes that the magnetic field has a crucial influence on the time condition for the perfect transfer of information,which no longer only depends on the physical properties of the spin chain.And the result has nothing to do with the number of the lattice points.Thus,according to the transfer needs,the reasonably magnetic field can be used to control the time condition for the perfect transfer of single-bit information.关键词
