SCIENTISTS DEMONSTRATE QUANTUM TELEPORTATION USING ELECTRONS

A team of researchers claim to have achieved quantum teleportation using individual electrons.

Quantum teleportation, or quantum entanglement, allows particles to affect each other even if they aren’t physically connected — a phenomenon predicted by famed physicist Albert Einstein.

Rather than a teleportation chamber out of a sci-fi movie, quantum teleportation transports information rather than matter.

Scientists have recently shown that pairs of photons — massless elementary particles — could form entangled qubits, the basic unit of quantum information. The discovery suggested that these qubits could transmit information via quantum teleportation.

Electron Qubits
The new research, however, marks the first time the same has been demonstrated using individuals electrons to form qubits.

“We provide evidence for ‘entanglement swapping,’ in which we create entanglement between two electrons even though the particles never interact, and ‘quantum gate teleportation,’ a potentially useful technique for quantum computing using teleportation,” John Nichol, an assistant professor of physics at the University of Rochester, co-author of the new paper published in Nature Communications this week, said in a statement. “Our work shows that this can be done even without photons.”

Allowing electrons to use quantum-mechanical interactions over a distance without touching could revolutionize the development of quantum computers. After all, semiconductors inside conventional computers use electrons to transmit information.

“Individual electrons are promising qubits because they interact very easily with each other, and individual electron qubits in semiconductors are also scalable,” Nichol said.

But passing this information over longer distances remains to be a big hurdle. “Reliably creating long-distance interactions between electrons is essential for quantum computing,” Nichol added.
