Quantum teleportation is an important step in improving quantum computing.<\/div>\n
\n

\u201cBeam me up\u201d is one of the most famous catchphrases from the Star Trek series. It is the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise.<\/p>\n

While human teleportation exists only in science fiction, teleportation is possible in the subatomic world of quantum mechanics\u2014albeit not in the way typically depicted on TV. In the quantum world, teleportation involves the transportation of information, rather than the transportation of matter.<\/p>\n

Last year scientists confirmed that information could be passed between photons on computer chips even when the photons were not physically linked.\u00a0<\/span><\/p>\n

Now, according to new research from the University of Rochester<\/a> and Purdue University<\/a>, teleportation may also be possible between electrons.<\/p>\n

In a paper published in Nature Communications<\/i><\/a> and one to appear in Physical Review X<\/i><\/a>, the researchers, including John Nichol<\/a>, an assistant professor of physics at Rochester, and Andrew Jordan<\/a>, a professor of physics at Rochester, explore new ways of creating quantum-mechanical interactions between distant electrons. The research is an important step in improving quantum computing, which, in turn, has the potential to revolutionize technology, medicine, and science by providing faster and more efficient processors and sensors.\u00a0<\/span><\/p>\n

\u2018Spooky action at a distance\u2019<\/b><\/h4>\n

Quantum teleportation is a demonstration of what Albert Einstein famously called \u201cspooky action at a distance\u201d\u2014also known as quantum entanglement. In entanglement\u2014one of the basic of concepts of quantum physics\u2014the properties of one particle affect the properties of another, even when the particles are separated by a large distance. Quantum teleportation involves two distant, entangled particles in which the state of a third particle instantly \u201cteleports\u201d its state to the two entangled particles.\u00a0<\/span><\/p>\n

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. A bit has a single binary value, which can be either \u201c0\u201d or \u201c1,\u201d but qubits can be both \u201c0\u201d and \u201c1\u201d at the same time. The ability for individual qubits to simultaneously occupy multiple states underlies the great potential power of quantum computers.<\/p>\n

Scientists have recently demonstrated quantum teleportation by using electromagnetic photons to create remotely entangled pairs of qubits.<\/p>\n

Qubits made from individual electrons, however, are also promising for transmitting information in semiconductors.<\/p>\n

\u201cIndividual electrons are promising qubits because they interact very easily with each other, and individual electron qubits in semiconductors are also scalable,\u201d Nichol says. \u201cReliably creating long-distance interactions between electrons is essential for quantum computing.\u201d<\/p>\n

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.<\/p>\n

Entangled pairs of electrons<\/b><\/h4>\n

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. The direction of the pole\u2014whether the north pole is pointing up or down, for instance\u2014is known as the electron\u2019s magnetic moment or quantum spin state. 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.<\/p>\n

The researchers used the technique to distribute entangled pairs of electrons and teleport their spin states.\u00a0<\/span><\/p>\n

\u201cWe provide evidence for \u2018entanglement swapping,\u2019 in which we create entanglement between two electrons even though the particles never interact, and \u2018quantum gate teleportation,\u2019 a potentially useful technique for quantum computing using teleportation,\u201d Nichol says. \u201cOur work shows that this can be done even without photons.\u201d<\/p>\n

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.<\/p>\n

This research is based upon work supported by the Defense Advanced Research Projects Agency, the Army Research Office, and the National Science Foundation.<\/p>\n
