    "abstract": "The three- spin chain with Heisenberg XY- interaction is simulated in a\nthree- qubit nuclear magnetic resonance (NMR) quantum computer. The evolution\ncaused by the XY- interaction is decomposed into a series of single- spin\nrotations and the $J$- coupling evolutions between the neighboring spins. The\nperfect state transfer (PST) algorithm proposed by M. Christandl et al [Phys.\nRev. Lett, 92, 187902(2004)] is realized in the XY- chain.",
