Researchers teleport information within a diamond

EurekAlert  June 28, 2019
Researchers in Japan have demonstrated quantum state transfer of photon polarization into a carbon isotope nuclear spin coupled to a nitrogen-vacancy center in diamond based on photon-electron Bell state measurement by photon absorption. The carbon spin is first entangled with the electron spin, which is then permitted to absorb a photon into a spin-orbit correlated eigenstate. Detection of the electron after relaxation into the spin ground state allows post-selected transfer of arbitrary photon polarization into the carbon memory. The study has big implications for quantum information technology…read more. Open Access TECHNICAL ARTICLE
