The Basics of Entanglement

Entanglement in quantum physics refers to the phenomenon where the quantum states of two or more particles become correlated in such a way that the state of one particle cannot be described independently of the state of the other particle(s). This phenomenon lies at the heart of many quantum protocols and applications, including quantum teleportation.

Quantum entanglement allows for the transmission of quantum information between entangled particles, regardless of the distance separating them, a concept essential for quantum teleportation.

Quantum teleportation is a remarkable quantum protocol that enables the transfer of quantum information from one location to another, without the physical transfer of the particles themselves. This process relies on the principles of entanglement and quantum superposition.

Initially proposed by Charles H. Bennett, Gilles Brassard, Claude Crépeau, Richard Jozsa, Asher Peres, and William K. Wootters in 1993, quantum teleportation has since become a fundamental tool in quantum information science.

The success of quantum teleportation hinges on the shared entangled state between the sender and receiver particles. By utilizing this entanglement, along with classical communication and Bell state measurements, quantum teleportation can faithfully transmit an unknown quantum state from one particle to another.

This process showcases the intricate connection between quantum entanglement and the transfer of quantum information, highlighting the profound implications of entanglement in quantum physics.
