"Quantum information processing is a key future technology. Algorithms based on quantum information have been proven to offer superior communication security and the ability to solve classes of computational problems that are not accessible to current classical information technology. Quantum entanglement and quantum measurements are two fundamental resources in quantum information. When combined, they enable one of the most dramatic applications of quantum mechanics: the teleportation of a quantum state between two remote systems.Solid-state systems promise a scalable implementation of quantum information technologies, but experiments aiming at long-range coupling of solid-state quantum registers are still in their infancy. Here we propose a set of ambitious experiments to demonstrate the long-range teleportation of solid-state quantum bits. We will entangle the electron spins of two remote Nitrogen-Vacancy (NV) centers in diamond by combining spin-photon entanglement and two-photon interference, and will subsequently demonstrate the teleportation of a nuclear spin state between two NV centers through quantum measurement and local qubit operations.This proposed first demonstration of teleportation with solid-state quantum bits will constitute a significant advancement in quantum information processing, and makes an important step towards the realization of quantum repeaters and quantum networks.The proposed experiments use advanced techniques from electron and nuclear magnetic resonance, single-molecule spectroscopy and quantum optics. This multidisciplinary research provides an excellent opportunity for the applicant to further strengthen and diversify his research expertise. Together with the extensive training in complementary skills provided by the host group, this fellowship will allow the applicant to reach professional maturity and be fully prepared for starting his own independent line of research."
