The paper proposes a quantum enhanced solution method based on quantum K-means for platform clustering and grouping in joint operations campaigns. The method first calculates the number of categories for platform clustering based on the determined number of task clusters, and sets the number of clustering categories in the classical K-means algorithm. By using the location information of the tasks, the clustering center points are calculated and derived. Secondly, the Euclidean distance is used as an indicator to measure the distance between the platform data and each cluster center point. The platform data is quantized and transformed into the corresponding quantum state representation. According to theoretical derivation, the Euclidean distance solution is transformed into the quantum state inner product solution. By designing and constructing a universal quantum state inner product solution quantum circuit, the Euclidean distance solution is completed. Then, based on the sum of squared errors of the clustering dataset, the corresponding quantum circuits are constructed through calculation and deduction. The experimental results show that the proposed method not only effectively solves the platform clustering and grouping problem under such action scales, but also significantly reduces the time and space complexity of the algorithm compared to the classical K-means algorithm.

Clustering is one of the most fundamental tasks in machine learning, and the k-means clustering algorithm is perhaps one of the most widely used clustering algorithms. However, it suffers from several limitations, such as sensitivity to centroid initialization, difficulty capturing non-linear structure, and poor performance in high-dimensional spaces. Recent work has proposed improved initialization strategies and quantum-assisted distance computation, but the similarity metric itself has largely remained classical. In this study, we propose a quantum-enhanced variant of k-means that replaces the Euclidean distance with a quantum kernel derived from the inner product between feature-mapped quantum states. Using the Iris dataset, we use multiple quantum feature maps, including entangled SU2 and ZZ circuits, to embed classical data into a higher-dimensional Hilbert space where cluster structures become more separable. We will also be testing using another dataset, namely the breast cancer dataset. Similarity between data points is computed through the inner product between two states. Our results show that this approach achieves improved clustering stability and competitive accuracy compared to the classical algorithm, with the SU2 feature map yielding an accuracy of 88.6 % on the Iris dataset and 91.0 % on the breast cancer dataset, despite operating on NISQ-feasible shallow circuits. These findings suggest that quantum kernels provide a richer similarity landscape than traditional distance metrics, offering a promising path toward more robust unsupervised learning in the NISQ era.
Abstract Quantum state clustering provides a powerful tool for quantum information processing. This paper focuses on the classification of single-qubit pure and mixed states via clustering algorithms, and discovers that the classical K -means algorithm has two limitations in clustering quantum states: the Euclidean distance cannot accurately reflect the similarity between quantum states, and the centroid update based on the arithmetic mean frequently fails to yield valid quantum states. To address these issues, we propose two distance metrics for quantum states: the dynamic distance and the Bloch distance, and adopt the K -medoids method to update the centroid, ensuring that the cluster center always remains a valid quantum state, thereby designing a quantum-data-adaptive clustering algorithm. Experimental results show that the dynamic distance achieves a clustering accuracy as high as 91.4 % , but at the cost of higher computational complexity. In contrast, the Bloch distance significantly reduces computational complexity while maintaining clustering performance comparable to that of the dynamic distance, achieving a clustering accuracy of 87.4 % . This paper provides a practical method for achieving efficient and reliable clustering of single-qubit quantum states.
Traditional clustering algorithms, such as k-means and DBSCAN, often face significant challenges when applied to big data. The computational complexity associated with distance calculations and nearest neighbor searches scales poorly with dataset size, limiting their effectiveness. This paper proposes a novel approach to clustering inspired by quantum measurement theory, specifically quantum-inspired nearest neighbor search. We leverage concepts from quantum mechanics, such as superposition and measurement, to design clustering algorithms that can efficiently identify clusters within high-dimensional datasets. The core idea is to treat the clustering problem as a measurement process, where candidate cluster centers are repeatedly measured against data points, and the most likely cluster centers are selected. The resulting algorithms aim to provide scalability improvements over conventional methods, particularly for datasets with a large number of features and data points. The effectiveness of the proposed algorithms is demonstrated through theoretical analysis and conceptual explanations, highlighting the potential benefits and future research directions.
The classical K-means clustering algorithm is widely used in various fields due to its simple implementation and efficient computation, but the classical K-means clustering algorithm relies on the random selection of the initial center of mass, which is prone to fall into the deadlock of local optimality. In order to break through this limitation, the quantum K-means clustering algorithm is introduced, which is able to explore multiple potential clustering center combinations at the same time through the parallelism of quantum computation, so as to have a greater probability of converging to the globally optimal solution. Quantum K-means clustering algorithms typically employ fidelity as a similarity measure between quantum states, and similarity is assessed by calculating the probability of overlap between quantum states. However, the fidelity only quantizes the pure state information of the quantum states and ignores the classical statistical features of the data itself, which may lead to unreasonable clustering boundaries in mixed state or noise interference scenarios. In response to the above problems, this paper proposes an improved quantum-classical hybrid similarity metric, whose core idea is to incorporate the dual constraints of quantum information and classical features.
This paper investigates the application of quantum algorithms to enhance clustering performance on big data. Traditional clustering algorithms often struggle with the computational complexity associated with large datasets and intricate data distributions. We propose and analyze the implementation of quantum k-means and quantum hierarchical clustering algorithms, leveraging quantum superposition and entanglement to potentially achieve significant speedups. The theoretical framework outlines the core concepts and mathematical formulations of these algorithms. We explore the potential for quantum algorithms to address the limitations of classical approaches, particularly in scenarios involving high-dimensional data and complex clusters. The research focuses on the algorithmic design, examining the key steps involved in transforming classical clustering problems into quantum computations. This work contributes to the emerging field of quantum data mining and provides a foundational understanding of how quantum computing can revolutionize data analysis tasks. The primary focus is on the theoretical aspects of quantum clustering and does not include experimental validation.
