Future Perspective of Quantum Cryptography for Smart Cities of the 21st Century

Introduction

Information and communication technology (ICT) is used in smart cities to increase operational effectiveness, share information with the public, and improve the quality of public services and citizen welfare (Anuj Tiwari & Kamal Jain, 2014). Technology is used by smart cities to offer services to their residents. Data collection involves the use of numerous technological techniques and sensors. The insights gained from the data obtained aid in operationally improving waste disposal, utility delivery, traffic flow, environmental management, and social service management. City officials can monitor the city in real-time and communicate easily with the population thanks to the usage of information and communication technology.

A well-developed and smart infrastructure with quality housing, education, and healthcare are given the highest priority in the smart city. A smart city must provide better habitation and provide better employment options to boost the economic growth of society. It should look forward to providing reliable and cost-effective measures with increased critical services. The resources of a smart city must be managed effectively to prevent depletion. Lastly, a smart city must have an improved transit network connectivity with the internet and proper use of cutting-edge technologies to serve community needs. These characteristics set smart cities apart from ordinary cities to serve as models for other towns looking to upgrade their infrastructure and spur urban economic growth. In India five cities, New Delhi, Hyderabad, Pune, Bhubaneshwar and Coimbatore are already identified with a few features. A brief discussion about these is presented in the following.
