Free-space Quantum Communication

May 15, 2023 - March 31, 2024


Work as project associate at PRL

  • Guide: Prof. Dr. R.P. Singh, Head, Atomic Molecular and Optical Physics(AMOPH) Division, Physical Research Laboratory

  • Worked on ’Effect of turbulence on key-rate in BB84 protocol’ experimentally under a team setting.

  • Worked on three node quantum network simulation and hands-on experimental techniques in Quantum Optics Lab.

  • Simulated Budget link equation for generation of key rate in BB84 and Quantum Networks.

  • Familiarized myself with a variety of quantum network simulators such as QKDNetSim, QuISP, NetSquid, QuNetSim, SQUANCH, SeQUeNCe and SimulaQron and chose SeQUeNCe for its flexibility and scalability.

  • Analyzed the BB84 protocol within the SeQUeNCe simulator, conducting an in-depth study on throughput, error rates and latency which offered valuable insights into the potential and restrictions of quantum networks

  • Progress report(until 10 July)
