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.
