摘要：

We present a procedure for quantum teleportation in a nuclear spin quantum computer in which quantum logic gates are implemented by using selective electromagnetic pulses. A sequence of pulses is combined with single-spin measurements in the sigma(z) basis for fast transfer of information in a spin quantum computer. We simulated this procedure,for quantum teleportation in a nuclear spin chain with a large number (201) of spins. The systematic errors generated in the process of teleportation due to the non-resonant effects are analyzed in detail. We demonstrate that a "2 pik" method provides a significant reduction of errors.
