“…Here, we focus on coined QWs. Different classes of coined QWs have been explored in the past decades, such as QWs with many coins [14][15][16][17][18][19][20][21][22][23][24][25][26], multiple walkers [27][28][29][30][31][32][33][34][35][36][37][38][39], and nonhomogeneous coin operators [40][41][42][43][44][45][46][47][48][49][50][51]. Very recently, coined QWs have found several applications ranging from quantum computation [37,52,53] to quantum information [18-26, 36, 38, 39, 48-50, 54].…”

Very recently, Lee et al. proposed the first secure quantum teleporation protocol, where quantum information shared by an arbitrary number of senders can be transferred to another arbitrary number of receivers. Here, by introducing quantum walks, a novel secure (n, m) quantum teleportation of shared quantum secret between n senders and m receivers is presented. Firstly, two kinds of (n, 2) teleportation schemes are proposed by n-walker quantum walks on the line, the first walker of which is driven by three coins, respectively, based on two kinds of coin operators: the homogeneous coins and the position-dependent coins. Secondly, by increasing the amount of the coins of the first walker to m + 1, the previous (n, 2) scheme can be generalized to (n, m) teleportation scheme. Then, we give the proof of the information security of our proposed scheme, in which neither any single nor subparties of senders and receivers can fully access the secret quantum information. Moreover, the projective measurements are needed, instead of the joint Bell measurements that are necessary in Lee et al.'s protocol. Our work can also be extended further to QWs on the cycle. This work provides an additional relevant instance of the richness of quantum walks for quantum information processing tasks and thus opens the wider application purpose of quantum walks.

“…An arbitrary twoqubit quantum-controlled teleportation scheme wherein the sender performs two Bell state measurements and the receiver performs a unitary operation to reconstruct the state was performed on an IBM quantum computer [31]. Perfect state transfer of entangled states by quantum walks with two coins was demonstrated on the IBM quantum experience [32].…”

The social infrastructure and needs of the various communities coexisting in a city are associated in considerably substantial and strong relationship with its surrounding environment. There are numerous parameters which influence the social infrastructure and community needs with respect to its integration with the land use of that city. Accessibility of proper terminals for public transportation, institutes, and hospitals parks etc. These parameters are studied along with parallel analysis of the total area covered and existing population of the city. Social infrastructures in a city have a large impact on the quality of life of the people in the urban centers. SAS Nagar (Mohali) is a counter magnet city of Chandigarh and one of the the most well-known planned city in Punjab, India. Mohali started developing as a counter magnet in the early 1990’s. It was initially known as Mohali village, a part of the Union Territory of Chandigarh. Mohali inhere with phases/ sectors including the new industrial areas, commercial centers and the educational institutions like as C-DAC Mohali in the vicinity of the residential areas. Mohali is spread over a total area of 167.67 sq. km out of which 32.58 sq.km is under the MC area with is characterized by very well planned areas. Despite of being a well-planned city of Punjab, India; Mohali still have a shortage of appropriate opportunity of services with low openness to the needs of the people. This study focuses on the relationship between land use and the social infrastructure with emphasis on the relationship analysis with geospatial planning techniques. The quality of life of people depends on the accessibility to quality of social and community infrastructure; it also impacts the migration pattern and the movement of daily commuters for their various reasons in the city. The advancement of the city is being anticipated as per the increase of the urbanization along with accessibility to proper social infrastructure, which satisfies the essential & functioning demand of the city. The development of the city is of two types’ i.e. compact development and sprawl development (depends on the density of population per sq.km). The assessment study of community infrastructure and social needs of Mohali includes various types of operational functioning parameters for study like; directional analysis, population wise analysis and area wise analysis. These social and community infrastructural needs have their own norms and standards for the city level services and as well as neighbourhood level assistance, which categorize their accessibility for the integrated land use pattern and population for services. By using open source GIS, the served areas and un-served areas along with their names are bring classified properly as per the given parameters.
