02 Guides
Five example guides
From building a chip model to computing gradients. Each guide includes runnable code and results.
01 · Define and inspect a chipDefine two coupled devices, inspect the Hamiltonian, fit dressed properties, and import a scqubits model.
02 · Spectra and parameter sweepsSweep a parameter, inspect an avoided crossing, and compare fluxonium spectroscopy and readout with published data.
03 · Dynamics, pulses and readoutSchedule pulses, simulate leakage and dissipation, and compare readout for different initial states.
04 · Model reductionUpdate and save a model, eliminate modes, partition components, and check a reduced model for a pulse sequence.
05 · Gradients and fittingCompute gradients for static properties and pulse sequences, and fit published fluxonium data.
