Quantum entanglement is amongst the strangest ideas of quantum mechanics and is being considered as an asset for revolutionary advances in quantum computing technologies. It arises due to the interaction between two quantum particles, which makes their quantum states independently ambiguous. The observation of one particle instantly affects the state of the other across significant spatial divides. Entangled particles exist in predetermined states even before observation but remain ambiguous until a practical measurement. This chapter surveys the underlying principles of quantum entanglement and its conceptual applications in quantum information processing. It further investigates the historical evolution and fundamentals of quantum theory to explain the role of quantum entanglement in the field of quantum computing. The discussion does not conclude at this point but briefly touches upon cutting-edge technologies like quantum teleportation, explaining the transmission of quantum states across large distances devoid of the physical transmission of matter. Though initially seen as science fiction, research has now begun on its practical applications towards enabling secure quantum communication.
