v0.0.1

QDesignOptimizer 0.0.1 Release

First release (0.0.1) of QDesignOptimizer!
This is an early release and the code in is a very active development stage. We welcome feedback, bug reports, and feature requests through our GitHub issue tracker.

Simulation Capabilities

In this release, QDesignOptimizer supports the following simulation types:

1. Eigenmode Simulations - Calculate resonant frequencies and quality factors of superconducting circuit components
2. Energy Participation Ratio (EPR) Analysis - Quantify energy distribution and nonlinear interactions between modes
3. Capacitance Matrix Simulations - Determine capacitive couplings between circuit elements

Available Study Classes

The following classes are available to configure and run simulations:

MiniStudy

• Core class for configuring eigenmode simulations and EPR analysis
• Define components, ports, junction parameters, and optimization modes
• Configure convergence parameters and meshing options

CapacitanceMatrixStudy

• Base class for all capacitance matrix simulations
• Extract static capacitance matrices between circuit components

ModeDecayIntoChargeLineStudy

• Calculate T1 limitations due to decay into charge lines
• Support for both grounded and floating qubit designs

ResonatorDecayIntoWaveguideStudy

• Estimate resonator linewidth (kappa) due to coupling to waveguides
• Support for λ/4 and λ/2 resonators
