The Harwell Quantum Cluster Quantum clustering (qc) is a class of data clustering algorithms that use conceptual and mathematical tools from quantum mechanics. qc belongs to the family of density based clustering algorithms, where clusters are defined by regions of higher density of data points. Cluster states are a special class of entangled states that serve as universal resources for measurement based quantum computation and possess an intrinsic symmetry protected topological order,.
The Harwell Quantum Cluster In this paper, we design, implement, and evaluate three hybrid quantum k means algorithms, exploiting different degrees of parallelism. indeed, each algorithm incrementally leverages quantum parallelism to reduce the complexity of the cluster assignment step up to a constant cost. Clustering algorithms are at the basis of several technological applications, and are fueling the development of rapidly evolving fields such as machine learning. in the recent past, however, it has become apparent that they face challenges stemming from datasets that span more spatial dimensions. In this work, we propose two novel measurement based quantum clustering algorithms. both algorithms are polynomial in time in terms of data to cluster, and the distance between the furthest points. further, they effectively remove the requirement of a black box. The significance of qlue lies in its potential to efficiently cluster data leveraging quantum computing, mitigating the escalating computational complexity encountered by classical algorithms as dimensions increase.

Here we present a quantum algorithm for clustering data based on a variational quantum circuit. the algorithm allows to classify data into many clusters, and can easily be implemented in few qubit noisy intermediate scale quantum devices. After discovering the cluster centers we are faced with the problem of allocating the data points to the different clusters. we propose using a gradient descent algorithm for this purpose. In this review we focus on the three most established quantum cluster approaches, the dynamical cluster ap proximation, the cellular dmft, and the cluster pertur bation theory formalisms.
