Quantum teleportation transfers a quantum state (e.g., a qubit in superposition) from one party to another without physically moving the qubit. It uses shared entanglement (e.g., a Bell pair) and classical communication. In a network, teleportation can hop through intermediate nodes (e.g., Alice to Charlie to Bob), enabling long-distance quantum communication for applications like quantum internet or distributed quantum computing. Noise can degrade the state, reducing fidelity.
Try it: Create a qubit with a chosen superposition. Distribute entanglement between nodes. Teleport the qubit and check if Bob receives the correct state. Toggle the intermediate node to see multi-hop teleportation. Enable noise to simulate real-world imperfections.
