About

QM Simulator

Features
Read full description

QM Simulator is a hands-on quantum physics atlas: 54 interactive simulation modules spanning the full arc from quantum foundations to quantum information, paired with 47 bilingual articles. Every computation and rendering happens on your device β€” no network, no sign-up. WHAT YOU CAN DO β€’ Play with parameters: adjust slit spacing, raise a potential barrier, tune cavity coupling β€” every chart recomputes in real time. β€’ Learn by level: Basics β†’ Advanced (perturbation, degeneracy, radiation) β†’ Topics (Bell inequalities, quantum error correction, Grover's algorithm), from high-school extension to university QM. β€’ Read linked notes: each article is tied to its simulation, with formulas and figures side by side β€” switch between Chinese and English anytime. β€’ Explore freely: Bloch sphere, hydrogen wavefunctions, blackbody radiation, Compton scattering, Kronig–Penney, BB84 quantum key distribution β€” from Planck's 1900 hypothesis to today's quantum computing. WHO IT'S FOR β€’ Physics students: turn textbook formulas into images you can see and manipulate. β€’ Educators & researchers: validate intuitions and demonstrate in class. β€’ The curious: no derivation skills needed β€” dial the parameters and build quantum intuition. HIGHLIGHTS β€’ 54 simulation modules, all driven by real physics computation (not pre-baked animations). β€’ 47 in-depth articles, fully bilingual, with figures and code. β€’ Fully offline: no ads, no purchases, no tracking, no account required. β€’ Chinese & English UI, follows system language. Educational use: QM Simulator works as a lecture-demonstration companion for quantum mechanics courses.
