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.

Do you know what’s inside an atom? The answer goes far beyond just electrons, protons, and neutrons. In Quantum Core, you’ll embark on an immersive 3D journey into the subatomic world. Help Max, an artificial intelligence inside a quantum device, restore its energy by collecting the universe’s most fundamental particles. As you progress, you’ll explore the atom from the inside and discover the particles and interactions that make up the Standard Model. Designed to make particle physics accessible and engaging, Quantum Core combines exploration, storytelling, and interactive gameplay to transform complex scientific concepts into an enjoyable learning experience.

Verdict

The call

The clearest difference is price: Quantum Core at Free against Monium's $3.99. Monium's advantage is iOS requirement (15.1 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
