How to Teleport Schrödinger's Cat

What does quantum teleportation actually transfer? This minutephysics explainer follows a qubit from Alice to Bob using shared entanglement and a classical message. The familiar cat illustration gives a difficult protocol a concrete starting point. Pair the 2017 video with the creator’s no-cloning explanation: transferring an unknown quantum state is different from making an independent perfect copy. The required classical communication also keeps the story grounded when science-fiction language suggests instant messaging or a transporter for people.
