Quantum teleportation is a protocol or technique that facilitates the transfer of the quantum state of a particle from one location to another without the physical movement of the particle itself. This concept within quantum information science investigates the principles and experimental methods required to achieve this state transfer using quantum entanglement and classical communication, highlighting its role as a foundational element for future quantum communication networks and distributed quantum computing. Key characteristics include the destruction of the original quantum state and the requirement for simultaneous classical communication to complete the transfer.
