    "abstract": "We investigate the non-nearest-neighbor interaction effect in 1-D spin-1/2\nchain model. In many previous schemes this long-range coupling is omitted\nbecause of its relative weak strength compared with the nearest-neighbor\ncoupling. We show that the quantum gate deviation induced by the omitted\nlong-range interaction depends on not only its strength but also the scale of\nthe system. This implies that omitting the long-range interaction may challenge\nthe scalability of previous schemes. We further consider how to suppress this\nunwanted effect. We propose a quantum computation scheme. In this scheme, by\nusing appropriate encoding method, we effectively negate the influence of the\nnext-nearest-neighbor interaction in order to improve the precision of quantum\ngates. We also discuss the feasibility of this scheme in 1-D Josephson charge\nqubit array system. This work may offer improvement in scalable quantum\ncomputing.",
