摘要： This paper presents a direct implementation scheme of the non-local multi-qubit controlled phase gate by using optical fibers and adiabatic passage. The smaller operation number for implementing the multi-qubit controlled phase gate and needlessness for addressing individually save physical resource and lower the difficulties of experiment. Meanwhile, the scheme is immune from some decoherence effects such as the atomic spontaneous emission and the fibers loss. In principle, it is scalable.
