This paradigm offers significant computational advantages over classical methods, particularly for NP-hard problems like phylogenetic tree reconstruction in evolutionary biology. Phylogenetic trees model the evolutionary relationships among species or genes, and their reconstruction is computationally challenging as the number of possible topologies grows exponentially with the number of taxa. To address this, biologists often rely on heuristic methods; however, recent work has shown that recursive graph-cut techniques can achieve high accuracy in phylogenetic inference, though at high computational cost. In this study, we present a quantum algorithm based on the normalized cut () criterion, enabling efficient recursive graph partitioning. Implemented using Quantum Annealing (QA) and the Quantum Approximate Optimization Algorithm (QAOA), demonstrating promising results on real quantum hardware for complex bioinformatics tasks.
