Teleportation protocol
Quantum teleportation is a protocol that transfers the unknown state of a qubit to a qubit elsewhere. The sender and receiver share a pre-entangled pair; The process also requires classical communication.

The matter of the first qubit is not moved and the state is not copied. The measurement distorts the original state at the sender; the receiver recreates the same quantum state with its correction to classical results. For this reason, the method does not provide faster-than-light communication.
city network experiment
In 2024, researchers demonstrated qubit-state beaming from an ion memory to a remote telecom photon on a 14.4-kilometer urban fiber link. Experimentation is an important building block for quantum networks; It does not mean irradiation of people or objects.
discussion question
How does transferring the state of an object without moving it change the concept of 'the same thing'?
