Resonant Quantum Mechanics is an educational app that introduces quantum states, quaternions, projection, hydrogen, and the periodic table through guided lessons and interactive 3D visuals. The app is designed for learners who want a more geometric and visual way to think about quantum mechanics. Each lesson combines clear written explanations with Unity-powered interactive scenes that help show how quantum states can be understood through rotation, orientation, phase, and higher-dimensional geometry. Topics include: Why geometry matters in quantum mechanics An introduction to quaternions Quaternionic state representation Projection and measurement Hydrogen energy levels Element structure and spectral patterns No login is required. The app is built as a learning experience for students, independent researchers, and anyone curious about quantum geometry.

Monium puts superconducting-qubit physics in your pocket — a mobile companion to the open-source scqubits library, built for researchers, students, and the quantum-curious. Pick a qubit, tune its parameters with live sliders, and watch the physics update in real time: • Energy spectrum vs. any swept parameter • Wavefunctions over the potential (and in the charge basis) • Matrix elements as a heatmap, and vs. the swept parameter • T1 / T2 coherence times per noise channel • Exact computed values behind every plot, as tables Supported qubits: Transmon, Tunable Transmon (SQUID), and Fluxonium. Built for real work: • Enter the Josephson energy the way you measure it — critical current, junction inductance, or room-temperature normal-state resistance (with a cryo/room ratio). • Save and reload presets per qubit. • Convergence indicators so you can trust the numbers. Everything runs on-device. No account, no ads, no tracking, no network — your work stays on your phone. Monium mirrors scqubits' conventions, and its results are tested against it: energy spectra, matrix elements and coherence times for all three qubits are checked against the Python library's own output.
