"Quantum teleportation is just the mind-blowing thought made possible by breakthroughs in subatomic physics"
When physicists say "teleportation", they are describing the transfer of key properties from one particle to another without a physical link.
Quantum teleportation is a process where quantum information (such as. the exact state of an atom or photon) can be transmitted (exactly, in principle) from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location.
There was a misconception that process of teleportation is physical, but a physical entity (alive) to travel no less faster than speed would be an impossible dream for now that is. Because it depends on classical communication, which can proceed no faster than the speed of light, it cannot be used for superluminal transport or communication of classical bits.
It also cannot be used to make copies of a system, as this violates the no-cloning theorem. Although the name is inspired by the teleportation commonly used in fiction, current technology provides no possibility of anything resembling the fictional form of teleportation.
While it is possible to teleport one or more Q-bits of information between two (entangled) atoms, this has not yet been achieved between molecules or anything larger. One may think of teleportation either as a kind of transportation, or as a kind of communication, it provides a way of transporting a Q-bit from one location to another, without having to move a physical particle along with it.
