  Overview

  Qublitz is a simulation tool aimed to lower the barrier to entry for students in high school and college trying to learn about Quantum Engineering. All simulations on Qublitz demonstrate the behavior of a single, two level qubit that occupies states between 1 and 0. Qublitz contains several simulation environments: Free Play, Gates Challenge, Step Pulse Challenge, Custom Qubit Query and Neutral Atoms. The engine behind every mode in Qublits is quantum_simulator.py which takes in given parameters to simulate the behavior of a single, two level qubit.

Free Play Mode

Free play mode is a sandbox contained in the 1_free_play_mode.py page and grants users access to most parameters necessary to simulate any qubit behavior they want to. There are two simulation modes in Free Play, the time domain and frequency domain. In the time domain, the user can determine both the qubit's properties and send a micorwave square pulse to see how it reacts in the Bloch sphere and graphs of the expected probability of the bit being in the 1 state. In the frequency domain, the user can observe the responsiveness of a qubit to a range of different driving frequencies (frequency of the pulses we influence the qubit with).

Gates Challenge [UNITARY HACK ISSUE]

The Gates Challange in the 2_gates_challenge.py page is, unlike free play mode, a directed game that follows a story structure with a tutorial and challenges for the user that get progressively more difficult. The challenges are focused on helping the user practice navigating along the bloch sphere using X and Y gates.

Step Pulse Challenge [UNITARY HACK ISSUE]

The Step Pulse Challenge in the 3_step_pulse_challenge.py page is also a directed game that follows a story structure with a tutotial and challneges. Unlike the Gates Challenge, these are focused on helping the user create gates using microwave pulses.

Installation

Libraries

Qublitz will initially be hosted as a Streamlit app. The relevant libraries for installation are as follows: streamlit pandas numpy plotly.graph_objects plotly.subplots plotly.express each page will also need to import run_quantum_simulation from quantum_simulator for the quantum simulator you will need to import qutip

Contributing

General Steps

To start contributing, fork the repository and clone the fork so you can run your version of Qublitz locally. Then, create a new branch git checkout -b feature-branch-name name the branch based on the feature you are working on. Eg. git checkout -b gates-challenge. Once your changes are made, commit them and push to branch. Finally open the pull request.

Specific Projects

For the Gates Challenge, you should take the existing 2_gates_challenge.py page and modify it. You may rewrite all of the code if you like but the gates page contains starter code for displaying the Bloch Sphere and showing how X and Y-Gates work. For the Step Pulse Challenge, you should take the existing 3_gates_challenge.py page and modify it. You may rewrite all of the code if you like but the gates page contains starter code for displaying the Bloch Sphere and input for creating a Step Pulse.
