Synthesizing NMR analogues of Einstein-Podolsky-Rosen states using   generalized Grover's algorithm
  By designing a proper unitary operator U, we synthesize NMR analogues of Einstein-Podolsky-Rosen states (pseudo-EPR states) using generalized Grover's algorithm on a nuclear magnetic resonance (NMR) quantum computer. Experiments also demonstrate generalized Grover's algorithm for the case in which there are multiple marked states.
