Tripartite GHZ state generation with trapped ion in an optical cavity
We present a single step scheme to generate, experimentally, maximally entangled tripartite GHZ state in a single ion, using trapped ion interacting simultaneously with a resonant external laser field and red sideband tuned quantized cavity field. Besides the simplicity of execution and short operation time, GHZ state generation is reduction free. Pacs: 03.67.-a, 42.50.-p, 03.67.Dd
