Quantum repeaters enable long-distance quantum communication by creating and extending entanglement between distant parties, like Alice and Bob. Quantum signals (e.g., entangled photons) weaken over distance due to loss in optical fibers. Repeaters solve this by dividing the distance into shorter segments, creating entanglement between adjacent nodes (e.g., Alice-Node 1, Node 1-Bob), and then "swapping" entanglement to connect the endpoints. Quantum memory stores entangled states to synchronize the process. This demo shows a simple repeater network with one node.
Try it: Click "Create Entanglement" to entangle adjacent nodes. Then, use "Perform Entanglement Swapping" to connect Alice and Bob. Adjust the loss rate to see its effect. Toggle quantum memory to simulate storing states, improving success.
