Demonstration of conditional quantum phase shift between ions in a solid

Longdell, Jevon; Sellars, Matthew; Manson, Neil


Because of their long coherence times, dopant ions have been considered promising candidates for scalable solid state quantum computing. Here we demonstrate a conditional phase shift between two qubits based on an optical transition of europium ions. The demonstration uses ensembles that have been selected from a randomly doped sample using spectral hole burning techniques. The electron dipoledipole interaction between the ions that usually causes instantaneous spectral diffusion is used...[Show more]
