density-matrix

This repository contains a new backend which can simulate noisy quantum logic circuits using the density matrix formalism.

Mandala is an E(3)-Equivariant Graph Neural Network Framework for Learning Electronic-Structure Operators with Observable Guidance based on e3nn.

Python utilities for running density matrix functional theory (DMFT) quantum chemical calculations.

We provide a density matrix framework to study Anderson localization and interplay between disorder and electronic interactions.

DeePTB: A deep learning package for tight-binding approach with ab initio accuracy.

Computational simulation of state fidelity and concurrence in a two-qubit entangled system under phase damping and amplitude damping noise as circuit depth increases.

a ML-SQM method

PHMT-4 Monte Carlo: heuristic classical numpy simulation (density-matrix membranes, crystallization mirror, Observer/Calibrator). SYNTHETIC results only. Not a consciousness theory, not quantum hardware.

A high-performance Quantum QCAD engine that uses Numba-JIT acceleration to map the "Sweet Spot" where algorithmic complexity meets physical noise. Unlike bloated enterprise kits, it provides a transparent, low-level look at how T_1 and T_2 decay shift the optimal depth of NISQ algorithms.
