Quantum Teleportation
What is quantum teleportation?
Quantum teleportation transfers a quantum state between locations using shared entanglement and two classical bits.
The protocol destroys the original state, consistent with the no-cloning theorem.
It is a core routine for quantum networking and for moving states within future processors.
