QUANTUM K - NEAREST NEIGHBORS
Quantum K-nearest neighbors (QkNN) is an advanced variant of the classical KNN algorithm that utilizes quantum computing to enhance performance and accuracy. By leveraging quantum parallelism and Grover's search algorithm, QkNN reduces the time complexity from O(N) to O(√N) for finding nearest neighbors. This approach involves encoding data into quantum states and performing quantum searches, enabling faster and more accurate classification.
QkNN is particularly promising in fields such as finance, cybersecurity, and artificial intelligence. As quantum computing technology advances, QkNN is poised to significantly impact machine learning and data analysis, offering a powerful tool for processing and analyzing large datasets efficiently.
