Research Projects

With the rapid deployment of 5G wireless networks in various parts of the world, academia, and industry have now started investigating the novel use cases and required technologies for the future 6G wireless networks. 6G wireless networks would be required to support high data rates, lower latency, and enhanced data privacy compared to the current 5G technology. Furthermore, we are witnessing the second quantum revolution, where the peculiar properties of quantum mechanics, such as superposition, entanglement, and collapse of quantum states, are utilized to design novel information and communication technologies (ICT). All the wireless technologies till now, starting from 1G to 5G, have been developed using the first quantum revolution, where the bulk or average properties of quantum mechanics are used to develop classical ICT. With the rapid advancement in quantum information technologies (QIT), it is expected that quantum technology will play a pivotal role in the development of future 6G wireless networks. The ultimate aim of 1G to 5G wireless communication system was to design efficient modulation, coding and signal processing techniques to reach the ultimate classical Shannon's capacity limits. In future 6G and beyond wireless networks, communications systems should be designed to reach the ultimate quantum limited capacity of wireless channels, which is given by Holevo's capacity limits. This project will design and analyze the communications systems from a quantum information theoretic viewpoint. Furthermore, the rapid development in quantum computing presents a grave threat to the security and privacy of current encryption schemes. Therefore, future 6G networks should be designed by keeping in mind the security threat from quantum computing technology to the current encryption schemes. This project will investigate these important research questions and investigate novel techniques for improving the performance of 6G wireless networks using QIT. The project will develop novel wireless communication systems that integrate quantum communication principles with 6G wireless technology, providing a foundation for ultra-fast, secure, and efficient communication systems. The project will develop novel mathematical models for quantum-enabled communication systems, analyze their performance, and perform simulations to characterize the performance of 6G wireless communication systems. The outcome of the project will help in the rational system design of future 6G wireless networks in the quantum era.
