Low-decoherence quantum information transmittal scheme based on the single-particle various degrees of freedom entangled states

In this paper, aiming at the problem that the quality of quantum encoding channels will get worse with transmittal distance increasing owing to the interaction between environmental noises and quantum systems. A new low-decoherence quantum information deferent scheme is proposed on the basis of the single-particle diverse degrees of freedom entangled states from dissimilar perspectives, its encoding channel and transmittal distance are separated. It can reduce amounts of noise interference in the information transmittal process from the origin by entanglement in various degrees of freedom of the single-particle, thus can better resist channel’s decoherence and has better deferent characteristics compared with other schemes. Besides, it can also solve the difficulty that cannot concurrently generate multiple remote entanglement pairs by preparation many single-particle entangling in different degrees of freedom. In sum, our proposed scheme is beneficial to promote the development of quantum information transmission and has a good innovation.
