Why Qubits Teleport INSTANTLY

Quantum teleportation works by first distributing entanglement between two quantum processors (QPUs), each holding one photon of an entangled pair. An unknown qubit is then subjected to a joint gate operation and measurement with the locally entangled photon. Due to entanglement, the quantum information is transferred to the remote processor nearly instantaneously. However, to actually recover and use the teleported qubit for further computation, the collapsed joint measurement result must still be sent over a classical network as classical bits, which limits the practical speed of the process.
