Quantum-Driven UAV Path Planning Using QUBO Model and Coherent Ising Machines

Guozhan Qiu, Riqi Lin, Jingxin Zhu +1 more

UAV path planning in multi-target mission scenarios presents complex optimization challenges, particularly when considering constraints such as energy consumption and time efficiency. This paper proposes a quantum computing-driven approach using the QUBO model, integrated with a coherent Ising machine (CIM) on an optical quantum platform, to optimize UAV path planning. By modeling the path planning problem as a QUBO formulation and utilizing quantum heuristic algorithms for optimization, the proposed method overcomes the bottlenecks of traditional heuristic algorithms in terms of computational efficiency and convergence speed. Experimental results demonstrate that the proposed approach significantly outperforms traditional algorithms such as Tabu Search and Simulated Annealing, particularly as the number of target points increases. This method provides a new approach for applying quantum computing to UAV path planning, promoting the practical use of quantum technology in industrial applications.

Coherent Ising machines: models for architectures and applications

Coherent Ising machines (CIMs) are an experimentally promising class of physics-based computational architectures that embed hard combinatorial optimization problems into systems of coupled nonlinear optical oscillators. The solution-finding mechanisms employed by CIMs feature complicated dynamical bifurcations occurring on a network scale, posing significant challenges to the development of theory and models for their underlying principles of operation. These difficulties are especially pronounced in the ultra-low-power or quantum regimes where the benefits in computational efficiency over conventional optimization algorithms are expected to be largest. We discuss some of our recent approaches and results at this intersection of dynamical systems theory and quantum model reduction, which have highlighted some potentially useful architectures and applications on the horizon for CIMs.

Large-scale Coherent Ising Machine

Today, world-wide efforts are being undertaken to explore non-von Neumann computation methods to overcome "the end of Moore's law". A promising approach is the coherent Ising machine (CIM), which utilizes a network of degenerate optical parametric oscillators for solving ground-state-search problems of the Ising model. Since its proposal in 2013 and the first proof-of-principle experiment in 2014, research on experimental CIMs has made rapid progress and now reached the level where we can find solutions to large-scale combinatorial optimization problems using a CIM system. In this paper, we review recent progress on CIMs, mainly focusing on the experimental side.
