I built a browser-based Quantum Playground for Jaynes-Cummings simulations, channels, Hamiltonians, and stabilizers.

A developer created a free browser-based quantum simulation tool for interactive quantum modeling, eliminating the need for Python-based frameworks like Qiskit or QuTiP. The platform, launched in March 2026, targets researchers and enthusiasts. The tool supports quantum channel analysis, including Kraus operator validation, Choi matrix computation, and structural inspection, streamlining noise and error modeling for quantum systems. Stabilizer formalism features enable users to construct projectors from generators (e.g., ["ZZI","IZZ"]), simplifying error-correction and state preparation workflows without local installations. A Hamiltonian playground offers pre-built models like Jaynes–Cummings and full Rabi, plus customizable driven/time-dependent systems with rotating frame support for dynamic simulations. Users can inspect matrices, simulate real-time dynamics, and export operators, with the developer actively seeking community feedback for future enhancements.
