    "abstract": "In this paper we consider limit theorems, symmetry of distribution, and\nabsorption problems for two types of one-dimensional quantum random walks\ndetermined by 2 times 2 unitary matrices using our PQRS method. The one type\nwas introduced by Gudder in 1988, and the other type was studied intensively by\nAmbainis et al. in 2001. The difference between both types of quantum random\nwalks is also clarified.",
