摘要：

The three-spin chain with a Heisenberg XY interaction is simulated in a three-qubit nuclear magnetic resonance quantum computer. The evolution caused by the XY interaction is decomposed into a series of single-spin rotations and the J-coupling evolutions between the neighboring spins. The perfect state transfer algorithm proposed by Christandl [Phys. Rev. Lett. 92, 187902 (2004)] is realized in the XY chain.
