Quantum Repeater
A quantum repeater is a device that helps extend the range of quantum communication, such as quantum internet or ultra-secure messaging. It works by dividing a long-distance link into shorter segments, creating entangled particles in each segment, and then linking these segments together through a process called entanglement swapping. This allows quantum information to be transmitted over much greater distances without loss or interference, overcoming one of the main challenges in quantum communication. Essentially, quantum repeaters act as intermediaries, preserving the delicate quantum states needed for secure and efficient data transfer across large networks.
