Quantum Repeater Chain

Interactive quantum-repeater simulator: compare direct single-photon entanglement distribution (success probability crashing exponentially with distance) against a repeater chain that breaks the link into short segments and stitches them together with entanglement swapping.

This simulator compares two strategies for distributing entanglement over distance: sending a single photon the whole way (top lane), versus breaking the link into short segments and joining them with entanglement swapping at intermediate repeater nodes (bottom lane). Fiber loss shrinks a single photon's survival chance exponentially with distance, so direct transmission collapses to near zero once the link gets long — while the repeater chain keeps every hop short enough to stay reliable, then stitches the pieces together. Adjust the total distance, the number of repeater nodes and the swap efficiency to see how the success-probability gap between the two approaches grows.

⚙ Under the hood

Compare direct single-photon entanglement distribution — success probability crashing exponentially with distance — against a quantum-repeater chain that splits the link into short segments and stitches them together with live entanglement-swapping events. Tune total distance, repeater count and swap efficiency and watch the success-probability gap widen.
