QDarts 1.0.5
A package for simulating realistic quantum dot arrays and their charge transitions.
Requires Python: >=3.8

# QDarts
Efficient **Q**uantum **D**ot **ar**ray **t**ransition **s**imulator. 

## Description
We provide an efficient simulation package, QDarts, generating realistic charge conductance signals from medium, more than 10 quantum dot arrays. By levering the polytope finding algorithm from [O. Krause, A. Chatterjee, F. Kuemmeth and E. van Nieuwenburg, Learning coulomb diamonds in large quantum dot arrays, SciPost Physics 13(4), 084 (2022)](https://scipost.org/SciPostPhys.13.4.084), the QDarts allows for:
- Transition finding in high-dimensional voltage space, 
- Selection of arbitrary cuts in the voltage space,
- Simulating effects of finite tunnel couplings,
- Including non-constant charging energies,
- Simulation of multiple sensor dot,
- Tunable noise parameters,
- User-friendly interface.

## Installation
The package supports Python 3.6 and later. To install the package, run the following command:

    pip install qdarts

## Manuscript
The package is based on the manuscript by [Krzywda et al., QDarts: A Quantum Dot Array Transition Simulator for finding charge transitions in the presence of finite tunnel couplings, non-constant charging energies and sensor dots](). The manuscript has been submitted to the SciPost Physics Codebases.

## Examples
The package provides a simple example to demonstrate the usage of the package. The example is available in the examples qatpack/examples folder. The example demonstrates the simulation of a quantum dot array with sensor dots, tunnel couplings, and non-constant charging energy. 

As a proof of principle, in the example we reconstruct the figure from the paper [Neyens et al.](https://journals.aps.org/prapplied/abstract/10.1103/PhysRevApplied.12.064049z), which shows the measured charge conductance signal from two sensor dots, which detect simultanous four-dot transition in the quantum dot array. The figure, visible below, has been computed in about a minute on a standard laptop.

guara 0.0.15
Framework to build UI test automation in Page Transactions pattern
Requires Python: >=3.8

# Guará
[![PyPI Downloads](https://static.pepy.tech/badge/guara)](https://pepy.tech/projects/guara)

Guará is a Python framework designed to simplify UI test automation.

### Syntax
```python
Application.at(apage.DoSomething [,with_parameter=value, ...]).asserts(it.Matches, a_condition)
```

### Example in Action
```python
from selenium import webdriver
from pages import home, contact, info, setup
from guara.transaction import Application
from guara import it

def test_sample_web_page():
    # Initialize the Application with a driver
    app = Application(webdriver.Chrome())
    # Open the web application
    app.at(setup.OpenApp, url="https://anyhost.com/")
    # Change language to Portuguese and assert content
    app.at(home.ChangeToPortuguese).asserts(it.IsEqualTo, content_in_portuguese)
    # Navigate to Info page and assert text presence
    app.at(info.NavigateTo).asserts(it.Contains, "This project was born")
    # Close the web application
    app.at(setup.CloseApp)
```
