πŸ§‘β€πŸ”¬ About Me

I'm a Physics postgraduate (M.Sc. @ Nagaon University) working at the intersection of quantum computing, machine learning, and full-stack development. My work spans building production web applications for government councils, designing AI-powered spectroscopic instruments, and researching quantum key distribution protocols.

  • πŸ” Currently: Designing a low-cost BB84-inspired Optical Key Distribution system under real-world constraints
  • βš›οΈ Research Intern at Harish-Chandra Research Institute (HRI) under Prof. Aditi Sen De β€” Quantum Communication via Entanglement (2025)
  • πŸ“„ Published Author β€” Article on ML-based honey adulteration detection via portable spectroscopy, in Physics Frontiers (Vol.-I) β€” Conference Proceedings Book, Assam Science Society & Bhawanipur Anchalik College (2025)
  • πŸ›οΈ Previously: Web & Software Dev Intern at Karbi Anglong Autonomous Council (KAAC)
  • πŸ“ Based in Nagaon, Assam, India

πŸ” Current Research

BB84-Inspired Optical Key Distribution System (Ongoing β€” M.Sc. Project)

Designing and experimentally analysing a low-cost implementation of quantum key distribution inspired by the BB84 protocol, tested under real-world optical and environmental constraints.

  • Photon polarization-based key exchange over free-space optical channels
  • Analysing quantum bit error rates (QBER) and eavesdropping detection sensitivity under practical noise
  • Goal: Affordable QKD hardware accessible outside high-end lab settings
  • Stack: Python Β· Optical hardware Β· Statistical modelling
