This lecture covers the concept of quantum entanglement, focusing on the special correlation between two systems known as qubits. It explains how this entanglement cannot be described by classical analogies and leads to the phenomenon of quantum teleportation, a unique communication channel between particles. The lecture also delves into Bell's inequalities and their application in quantum cryptography, as well as superdense coding. Various properties and examples of entangled states are discussed, showcasing the intricate nature of quantum information and its potential applications.
