Description by Jens Koch Written by the developer, not by AppBrain. Click to read.
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.
