Quantum technology is an emerging field of physics and engineering, which relies on the principles of quantum physics. It is about creating practical applications—such as quantum computing, quantum sensors, quantum cryptography, quantum simulation, quantum metrology and quantum imaging—based on properties of quantum mechanics, especially quantum entanglement, quantum superposition and quantum tunnelling.

Centre for Quantum Information, Communication and Computing is an Interdisciplinary Research Centre located in Indian Institute of Technology, Madras. The Center of Excellence has distinguished scholars from diverse disciplines and backgrounds, such as the Department of Physics, Electrical Engineering and Computer Science.
