用限制场控制自旋链中的量子态转移

Controlling quantum state transfer in spin chain with the confined field

Bing Chen, Z. Song, C. P. Sun

摘要:

作为量子态转移的谱宇称匹配条件(SPMC)的证明,我们用解析和数值方法研究了在外部切向受限磁场中海森堡链中单磁振子态的传输.结果表明,当系统的色散关系近似满足SPMC时,初始高斯波包可以在较长的距离上近似理想地恢复到对应位置。

英文摘要:

As a demonstration of the spectrum-parity matching condition (SPMC) for quantum state transfer, we investigate the propagation of single-magnon state in the Heisenberg chain in the confined external tangent magnetic field analytically and numerically. It shows that the initial Gaussian wave packet can be retrieved at the counterpart location near-perfectly over a longer distance if the dispersion relation of the system meets the SPMC approximately.
