While human teleportation currently exists only in science fiction, teleportation is possible now in the subatomic world of quantum mechanics -- albeit not in the way typically depicted on TV.
In the quantum world, teleportation involves the transportation of information, rather than the transportation of matter. Quantum teleportation involves two distant, entangled particles in which the state of a third particle instantly "teleports" its state to the two entangled particles. However, the superposed quantum state of two entangled particles cannot be split into states of two individual particles. Coherence and entanglement play a critical role in emergent fields such as nanoscale thermodynamics and quantum biology and in technologies such as quantum teleportation and quantum cryptography.
However, our understanding and quantitative characterisation of coherence as an operational resource is still very limited. It is well known that entanglement stems from the superposition principle, which is also the essence of coherence. Then how can one resource emerge quantitatively from the other? The Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
