Quantum teleportation is a protocol within Quantum Information Theory that enables the transfer of an unknown quantum state between distant parties using shared entanglement and classical communication, without violating the no-cloning theorem due to the destruction of the original state at the source. This mechanism relies on resource inequalities defining the equivalence between two ebits of shared entanglement (Bell pairs), one qubit sent via a noisy or absent channel, and necessary logarithmic bits of classical information exchange. Theoretically, it establishes that quantum states can be transported through a network only when combined with pre-established non-local correlations and classical signaling, distinguishing itself from superdense coding by its dual role as the reverse operation converting quantum communication resources into state transfer capabilities.
