Quantum Physics: Visual Lab is a beginner-friendly way to explore the strange and fascinating world of atoms, photons, electrons, and quantum behavior. Learn step by step with short lessons written in plain language. Build your understanding of wave-particle duality, the double-slit experiment, superposition, observation and measurement, entanglement, uncertainty, tunneling, qubits, photons, orbitals, quantum fields, and modern quantum technology. Open the Visual Lab to see abstract ideas in motion. Watch interference patterns form, compare particle and wave behavior, explore superposition, adjust uncertainty, observe tunneling probabilities, investigate entanglement, and visualize a qubit. Check your understanding with lesson-based quizzes and a daily quantum question. Review explanations after each answer, track your quiz accuracy, complete lessons, keep a study streak, and earn achievement badges as you progress. Use the glossary to look up key terms quickly, then visit the scientist timeline to learn about the people who shaped quantum physics, including Planck, Einstein, Bohr, Heisenberg, Schrodinger, Dirac, Feynman, and more. Features: - 18 beginner-focused quantum physics lessons - 7 interactive visual simulations - 110 quiz questions with explanations - Daily quantum question - Progress tracking, quiz accuracy, streaks, and achievements - Glossary of key quantum terms - Scientist timeline with short biographies - Plain-language examples, formulas, misconceptions, and real-world applications - Optional lifetime unlock to remove ads and open all premium content Quantum physics can feel mysterious, but it does not have to feel unreachable. Visual Lab turns difficult ideas into clear explanations and interactive moments you can explore at your own pace. Educational note: This app is designed for beginner learning and intentionally simplifies some advanced physics concepts.

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 is validated against it, so the numbers match the desktop tool you already trust.
