It has been shown classically that combining two chaotic random walks can yield an ordered(periodic) walk. Our aim in this paper is to find a quantum analog for this rather counter-intuitive result. We study chaotic and periodic nature of cyclic quantum walks and focus on an unique situation wherein a periodic quantum walk on 3−cycle graph is generated via a deterministic combination of two chaotic quantum walks on the same graph.

India is a motherland of large number diverse communities. Tribes are called as ‘Adivasi’ or socially backward class people mainly lives in forest, hills, and rural remote area. There are more than 8.6 % of total population (Wikipedia) are tribes with around 645 tribes communities in India. In the question of tribal education a huge number of students are out of school, the literacy rate is below of national average literacy and significant literacy gap is found among the tribal male and female. So, in this juncture the objectives of this review based study are a comprehensive understanding regarding the Tribal dropout based on the existing literature reporting govt. initiatives and reasons of dropout in India. The study identified many reasons behind the dropout and explored equity and equality related issues faces challenges and a huge number of tribal children are out of school and deprived from accessing quality education
