Introduction

This page provides a way how to simulate the spin qubit dynamics with the CCEX software. The source code of this software can be found in CCEX GitHub Repository

About the simulation

In this code, we simulate the qubit dynamics in the presence of the bath spins.

You can simulate the spin qubit dynamcis with the following methods:

Cluster correlation expension method (CCE method)
CCE-NeNn method
Generalized CCE method
Partition CCE method

You can obtain the following physical quantities of qubit for evolving time:

Coherence function
Density matrix (gCCE method only)
Noise function (To be done for CCE, gCCE)

Installation

$ git clone https://github.com/HuijinPark/CCEX.git

Requirement

Note

MakeFile Path should be changed..

Usage Instructions

To run the code using mpirun , use the following command :

$ mpirun -n process_number code_path -f input_file

process_number : The number of processes to run.
code_path : The path to your executable code.
-f input_file : The input file required for the code to run. (input file should be .json file)

example

$ mpirun -n 4 /usr/local/bin/mycode -f data/input.json

For more detailed instructions, see the Getting Started.

Update

(2025. 04. 14) Code documents are updated. Hyperfine mediated term in CCE method can be added. Knight shift in CCE method can be added
