Well, this is no longer fantasy, but real-life teleportation using quantum entanglement is more likely to improve communication and national security than to be used for travel or space exploration.
In quantum mechanics, teleportation has a very different meaning. Scientists at University of Science and Technology, located in Shanghai, achieved quantum teleportation at a record distance by sending entangled photons from Tibet to the Micius satellite in orbit miles above the Earth, according to Space.
When two quantum objects are entangled, they are connected so that if one is disturbed, the other will also immediately change, no matter how far apart they are from each other. Quantum teleportation is an important means for transmitting information in quantum computing. While a typical computer consists of billions of transistors, called bits, quantum computers encode information in quantum bits, or qubits. The ability for individual qubits to simultaneously occupy multiple states underlies the great potential power of quantum computers.
Scientists have recently demonstrated quantum teleportation by using electromagnetic photons to create remotely entangled pairs of qubits. Qubits made from individual electrons, however, are also promising for transmitting information in semiconductors.
Creating entangled pairs of electron qubits that span long distances, which is required for teleportation, has proved challenging, though: while photons naturally propagate over long distances, electrons usually are confined to one place.
In order to demonstrate quantum teleportation using electrons, the researchers harnessed a recently developed technique based on the principles of Heisenberg exchange coupling. An individual electron is like a bar magnet with a north pole and a south pole that can point either up or down. If certain kinds of particles have the same magnetic moment, they cannot be in the same place at the same time.
That is, two electrons in the same quantum state cannot sit on top of each other. If they did, their states would swap back and forth in time. The researchers used the technique to distribute entangled pairs of electrons and teleport their spin states. The results pave the way for future research on quantum teleportation involving spin states of all matter, not just photons, and provide more evidence for the surprisingly useful capabilities of individual electrons in qubit semiconductors.
