Quantum Repeaters

Quantum repeaters are devices designed to extend the range of quantum communication, enabling secure information transfer over long distances. They work by using entangled particles, which are pairs of particles that share a quantum state. When one particle is manipulated, its partner reflects that change instantly, regardless of distance. Quantum repeaters help to overcome the challenge of signal loss in traditional fiber-optic cables by generating new entangled pairs at intervals, allowing messages to be transmitted reliably over vast distances. This technology is crucial for building a future quantum internet with enhanced security and speed.
