Ignoring the complex math and non-intuitive quantum effects, in its simplest form quantum teleportation has been used for hundreds of years as a way to recreate atoms and later recreate complete objects by information exchange and not material exchange.
It is not a way to instantly transport an object because to pass the information needed by the teleportation requires a classical communication link between the two locations which is limited by the speed of light. Just as the telegraph hundreds of years before had required wires to transmit information, so quantum teleportation requires an ordinary classical communication channel, be it radio, light or other. And because the classical channel is required the size of the object “teleported” is limited by the amount of information and speed of the communications channel.
And the amount of information grows exponentially as the objects become more complex . . .
