Physicists Teleport Quantum Information

Scientists teleported quantum information inside of a diamond. It could be a breakthrough for quantum computing and how we will share and store information in the future. The team of scientists were from Japan’s Yokohama National University. The study was published in the journal Communications Physics.

“Quantum teleportation permits the transfer of quantum information into an otherwise inaccessible space,” Hideo Kosaka, an engineer at Yokohama National University in Japan, said in a press release. “It also permits the transfer of information into a quantum memory without revealing or destroying the stored quantum information.” 

The researchers built an oscillating magnetic field around the diamond. Then using microwave and radio waves, the team manipulated an electron and a carbon isotope inside a defect in the diamond, known as a nitrogen-vacancy center, entangling the electron and the nucleus of the carbon atom. Then they had the electron absorb quantum information in a photon. 

The team of scientists confirmed the success of the transfer when they saw the photon’s polarization state transferred to the carbon of the diamond.
