Analyses (qiskit_metal.analyses)#

Module containing all Qiskit Metal analyses.

Analysis Core#

QAnalysis(*args, **kwargs)

QAnalysis is the core class from which all Metal analysis classes are derived.

QSimulation([design, renderer_name])

A subclass of QAnalysis, intended to standardize across all Analysis classes select and name renderers.

Hamiltonian#

Hcpb([nlevels, Ej, Ec, ng])

Hamiltonian-model Cooper pair box (Hcpb) class.

Hcpb_analytic([Ej, Ec, ng])

Analytic version of Hamiltonian-model Cooper pair box (Hcpb) class.

HO_wavefunctions

This code calculations the wavefunction(s) of the simple harmonic oscillator corresponding to an LC circuit.

transmon_analytics

This code calculates the energy eigenvalues of the transmon qubit cooper pair box as a function of the offset charge and plots the corresponding results.

Electromagnetic & quantization / parameter extraction#

cpw_calculations

For calculations of CPW parameters.

kappa_calculation

This code calculates the photon loss (kappa) due to the capacitive coupling between CPWs and input/output transmission lines in a quantum circuit.

Sweeping Options#

Sweeper(parent)

The methods allow users to sweep a variable in a components's options.

Quantization#

LOManalysis([design, renderer_name])

Performs Lumped Oscillator Model analysis on a simulated or user-provided capacitance matrix.

EPRanalysis([design, renderer_name])

From an input eigenmode dataset, apply the Energy Participation Ratio analysis method.

lumped_capacitive

Handles the capacitive simulation of a transmon pocket model.

Simulation#

LumpedElementsSim([design, renderer_name])

Compute Capacitance matrix using the selected renderer.

EigenmodeSim([design, renderer_name])

Compute eigenmode, then derive from it using the epr method.

ScatteringImpedanceSim([design, renderer_name])

Uses drivenmodal simulation to extract the impedance.
