Welcome to our research group “Quantum Technology (Q-Tech) Research” at the department of physics, School of advanced sciences (SAS), Vellore Institute of Technology, Vellore, Tamil Nadu, India. Our group focuses on the quantum photonics application of two-dimensional materials for quantum communication, energy harvesting, and quantum memory/sensing applications. Two-dimensional materials are an excellent material platform for both quantum communication device fabrication and photovoltaic/green hydrogen devices. Furthermore, we also use metal/dielectric nanoantenna for quantum technolgical applications such as integrated quantum communication devices, Green Hydrogen generation, and quantum memory/sensing devices.
