Description:
Robust entanglement at room temperature is a necessary requirement for practical applications in quantum technology. We demonstrate the creation of bipartite- and tripartite-entangled quantum states in a small quantum register consisting of individual 13C nuclei in a diamond lattice. Individual nuclear spins are controlled via their hyperfine coupling to a single electron at a nitrogen-vacancy defect center. Quantum correlations are of high quality and persist on a millisecond time scale even at room temperature, which is adequate for sophisticated quantum operations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neumann, P -- Mizuochi, N -- Rempp, F -- Hemmer, P -- Watanabe, H -- Yamasaki, S -- Jacques, V -- Gaebel, T -- Jelezko, F -- Wrachtrup, J -- New York, N.Y. -- Science. 2008 Jun 6;320(5881):1326-9. doi: 10.1126/science.1157233.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉3.Physikalisches Institut, Universitat Stuttgart, Pfaffenwaldring 57, D-70550 Stuttgart, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18535240" target="_blank"〉PubMed〈/a〉
