Quantum Computing for Traveling Salesman Problem

Published:Dec 30, 2025 16:04
1 min read
ArXiv

Analysis

This paper explores the application of quantum computing, specifically using the Ising model and Variational Quantum Eigensolver (VQE), to tackle the Traveling Salesman Problem (TSP). It highlights the challenges of translating the TSP into an Ising model and discusses the use of VQE as a SAT-solver, qubit efficiency, and the potential of Discrete Quantum Exhaustive Search to improve VQE. The work is relevant to the Noisy Intermediate Scale Quantum (NISQ) era and suggests broader applicability to other NP-complete and even QMA problems.

Enhanced Distributed VQE for Large-Scale MaxCut

Published:Dec 26, 2025 15:20
1 min read
ArXiv

Analysis

This paper presents an improved distributed variational quantum eigensolver (VQE) for solving the MaxCut problem, a computationally hard optimization problem. The key contributions include a hybrid classical-quantum perturbation strategy and a warm-start initialization using the Goemans-Williamson algorithm. The results demonstrate the algorithm's ability to solve MaxCut instances with up to 1000 vertices using only 10 qubits and its superior performance compared to the Goemans-Williamson algorithm. The application to haplotype phasing further validates its practical utility, showcasing its potential for near-term quantum-enhanced combinatorial optimization.
Reference

“The algorithm solves weighted MaxCut instances with up to 1000 vertices using only 10 qubits, and numerical results indicate that it consistently outperforms the Goemans-Williamson algorithm.”
