Melvin is an innovative computer program designed to assist quantum physicists in the development and discovery of novel and beneficial quantum experiments. It was developed by Mario Krenn, marking a significant advancement in the field of quantum physics.

Here, I have partially reimplemented Melvin, originally developed in Mathematica, in Python utilizing SymPy for symbolic mathematics.

Prerequisites:

To run the code from this repository, you need to install SymPy - version 1.3.

Codes

Examples on creating quantum states and symbolic transformations:
Related Mathematica codes are in the branch Mathematica_Codes:

• The SimpleHOMExample program shows how to work with quantum states, and how the symbolic transformations work.

    SimpleHOMExample.nb
    SimpleHOMExample.py

• The CalcSRV program is a full version which searches for 3-particle high-dimensionally entangled states with existing optical elements.

    CalcSRV.nb
    CalcSRV.py

• The SRVCaseCheck code is for checking whether a optical setup can produce 3-particle maximally entangled states.

    SRVCaseCheck.py

• Here I add one more code for checking the SchmidtRankVector of a 4-particle maximally entangled state
  More details about Schmidt Rank Vectors, refer to Structure of Multidimensional Entanglement in Multipartite Systems.
