Project: Generation of Entangled Photons and its Applications to Quantum Computation and Information Processing (Q-46)

Institute: Indian Institute of Technology (IIT), Jodhpur

Principal Investigator: Dr. V. Narayanan

Co-Principal Investigator: Dr. Subhashish Banerjee

Co-Principal Investigator: Prof. Anirban Pathak

This research project is collaborative in nature, involving Dr. V. Narayanan (PI), Dr. Subhashish Banerjee (Co-PI) from IIT-Jodhpur and Dr. Anirban Pathak (Co-PI) from JIIT, Noida. The investigation would be a mixture of study of theoretical and experimental facets of laser matter interactions that has applications in quantum information and computation. Further, this project is envisaged to contribute in creation of skilled manpower in the domain of quantum information and related domain.

In this project:

  • Entangled Photons will be generated by pumping the Nonlinear Crystal (eg. BBO) by a Short-Pulsed Laser and it will be characterized by various methods.
  • Efficient generation of entangled photons are also envisaged.
  • Experimental investigation for detecting entangled photons between two-locations and higher entangled states will be carried out.
  • The development of Single Photon Source and its Characterization, Potential Applications of it in the domain of defence will be explored.
  • Theoretical investigations relevant to this project with a focus on the effect of Noise on the Efficiency of the Quantum Communication chemes.
