Light and Matter Physics
Urbasi Sinha heads the Quantum Information and Computing (QuIC) laboratory at RRI. This is one of the first labs in India to manufacture and establish the usage of entangled and heralded single photon sources towards various applications in quantum science and technologies. The current research areas include experimental secure quantum communications including quantum key distribution (QKD) in free space, fiber and integrated photonics, Quantum Teleportation as well as Device Independent random number generation; higher dimensional quantum information processing including photonic quantum computing; fundamental tests in quantum optics and quantum mechanics including generalized measurements and various studies based on static and dynamic properties of entanglement. One of the key projects being led by the lab is a collaborative project between RRI and the Indian Space Research Organization (ISRO) called "Quantum Experiments with Satellite Technology", which is India's first funded project on satellite based long distance quantum communications.
