Welcome to the github page of the DM (Density Matrix) solver. This is a simple program that solves the time evolution of a density matrix, given a time dependent Hamiltonian. Most of the commonly used pulseshapes in experiments are supported. Also functionality to simulate pink/white noise is included. To speed up the execution of the code, it it written in c++. Not to worry though! The code just needs to be compiled and can be fully accessed from the python API.
Before you can compile the library, you will need to install the following dependencies:
Compile and install all the c++ libraries as given in the requirements. In Linux/OS X (use brew) you can install them using your package manager. On Windows the installation will be mode cumbersome.
The libraries can be compiled using the makefile by running the following command in the DM_solver/lib/makefile folder:
makeIf using brew in OS X, it is likely that clang will will be selected as your default compiler, this can resolved by adjusting the CC and CCX variables in the makefile, e.g. when gcc-12 is installed:
CC = gcc-12
CXX = g++-12
It might by that you need to manually include the armadillo library (e.g. an error on #include <armadillo>), this can by done by adjusting the ARMA_lib variable in the makefile to the location where the library is located.
The examples in the example folder should be self explanatory.
