Abstract:

Quantum entanglement is one of the most remarkable phenomena in quantum physics, enabling correlations between particles that remain connected regardless of distance. This paper investigates the theoretical foundations of quantum entanglement, its experimental realizations, and its revolutionary applications in quantum computing. Entanglement provides the basis for quantum algorithms, quantum cryptography, and quantum teleportation, paving the way for technologies that outperform their classical counterparts. A thorough examination of Bell’s inequality, entanglement measures, and modern technological implementations highlights the transformative potential of this field. While significant strides have been made, challenges such as decoherence and large-scale entanglement generation persist, driving further research into this profound aspect of quantum mechanics.
