量子系统的完全能控性

Complete controllability of quantum systems

S. G. Schirmer, H. Fu, A. I. Solomon

摘要:

建立了$N$能级量子系统在单个控制脉冲作用下的完全可控性的充分条件。结果特别适用于莫尔斯和谐振子系统,以及一些系统的退化能级。Morse和谐振子作为分子键的模型,并且使用频率选择性脉冲序列来一次解决单个跃迁的标准控制方法对于这样的系统要么不适用要么仅具有有限的效用。

英文摘要:

Sufficient conditions for complete controllability of $N$-level quantum systems subject to a single control pulse that addresses multiple allowed transitions concurrently are established. The results are applied in particular to Morse and harmonic-oscillator systems, as well as some systems with degenerate energy levels. Morse and harmonic oscillators serve as models for molecular bonds, and the standard control approach of using a sequence of frequency-selective pulses to address a single transition at a time is either not applicable or only of limited utility for such systems.
