QSW_MPI is a python package developed for MPI-parallelised time-series simulation of continuous-time quantum stochastic walks. This model allows for the study of Markovian open quantum systems in the Lindblad formalism, including a generalization of the continuous-time random walk and continuous-time quantum walk.

Pre-domain framework for transition dynamics and structural enforcement

3 different types of quantum walks: a. Hadamard Walk in 1D.; b. 1D quantum walk following the Su Schrieffer Heeger (SSH) model; c. 2D quantum walk.

Reverse quantum walk for search on graph structures

(In progress) Literature review of QW

In this repository, you will find MATLAB codes that generate probability distributions of a quantum walk. Specifically, I am uploading MATLAB codes for simulating a quantum walk on a line without decoherence, a quantum walk on a line under decoherence, and a classical random walk on a line.

qwalkr: Handle Continuous-Time Quantum Walks with R

2-step discrete quantum walk on a 4-node cycle using Hadamard coin (1 coin qubit, 2 position qubits).

A python package for discret time quantum walk with custom shift and coin operators

Topological diagnostics for discrete-time quantum walks on non-orientable surfaces (Möbius band, Klein bottle) — Floquet operators, chiral winding numbers, and Z₂ invariants, with a PennyLane circuit backend.

Study and patched re-implementation of the MNRS quantum walk search for the Constrained Subset-Sum Problem (CSSP), based on Lancellotti, Perriello, Barenghi and Pelosi, Solving the Subset Sum Problem via Quantum Walk Search, IEEE Transactions on Computers vol. 75, n. 1, 2026 (DOI).
