Visualization tool for the Feynman Path Integral applied to quantum circuits

Type an M x M matrix for your open quantum system Hamiltonian, and give a spectral density (analytic or numerical). FeynDyn gives the density matrix dynamics according to the Leggett-Caldeira bath or the Feynman-Vernon bath at any temperature. Can do up to 16 qubits (65536 levels) and infinitely many bath modes.

feyntrop integrates Feynman graphs using tropical sampling

Compute master integrals using commutative and noncommutative methods from computational algebraic geometry

MPMC++ | This is the MPMC (github.com/mpmccode/mpmc) molecular simulator rewritten in C++ in order to add the ability to integrate Feynman Path Integrals and "multi-system" stat mech ensembles (e.g. Gibbs).
