Welcome to My GSoC 2025 Journey

Hi, I’m Vanshaj Bindal – a MSc Physics graduate with a passion for quantum information, theoretical physics and newfound interest in open-source development. I’m thrilled to be participating in Google Summer of Code 2025 with NumFOCUS, working on an exciting project that bridges quantum physics and computational tools.

This blog is a record of my GSoC experience, technical discoveries, and the fascinating world of quantum simulation software.

About the Project

Hamiltonian Library for QuTiP

I’m developing a comprehensive Hamiltonian Library for QuTiP (Quantum Toolbox in Python), one of the most widely-used quantum simulation frameworks. Currently, QuTiP users must frequently recreate common quantum system Hamiltonians from scratch, leading to redundant work and potential inconsistencies.

What I’m Building:

  • Ready-to-use implementations of frequently used quantum systems including Jaynes-Cummings, Rabi, Dicke, and various spin-chain models
  • A standardized API with JSON serialization for cross-platform compatibility
  • Time-dependent parameter support for dynamic quantum systems
  • LaTeX representation capabilities for clear mathematical documentation
  • Comprehensive documentation, tutorials, and seamless integration with QuTiP’s existing functionality

Technologies & Tools:

  • Primary: Python, QuTiP, NumPy, SciPy
  • Development: Git, GitHub, Jupyter Notebooks
  • Documentation: LaTeX, Matplotlib
  • Testing: pytest framework

Mentors: Alex Pitchford, Neill Lambert, Eric Giguere and Simon Cross

This project will enhance the user experience for quantum researchers and reduce redundancy in quantum simulations.
