About

A simulator aim at simulating and solving Transmon based qubit-coupler-resonator system.

This program is directed by Dr. Fei Yan, BAQIS. The original code structe is adoppted from Mr. Pan Shi, Wuhan University & BAQIS, and contributed by Mr. Jiheng Duan and Dr. Ruixia Wang, and Dr. Zhen Chen.

Look up the PyPI page: https://pypi.org/project/qusim/

User_Guide

Install (use pip)

pip install qusim

Requirement

You are required to install all these python packages in the system for running this simulator. See requirements.txt.

  • Python, version >= 3.10

Installing virtual environment using conda conda -n env_name python=python_ver -ipython

  • qutip, version >= 4.6.3
  • matplotlib==3.8.3
  • mpmath==1.3.0,
  • pillow==10.2.0,

Download

Just downloading the entire folder.

There is also a release.

Usage

We have two version: the transmon_system.py and arb_qubit_system.py

The detailed tutorial are shown in folder tutorial/~, including required imports, define a system, what inside a system, scan zz-coupling, scan energy level, driven system dynamics, single qubit gate calibration, and DRAG calibration.

Features

Our simulator includes the following features:

  • Support multiple qubits
  • Multiple initial state simulation
  • Internal plot function
  • DRAG
  • Generalized for any qubit
  • Good data saving and loading functions
  • Tunable coupler helper
  • Aviod crossing helper

Todo list

Stop lazying
