We uncover new features on the study of a two-level atom interacting with one of two cavities in a coherent superposition. The James-Cummings model is used to describe the atom-field interaction and to study the effects of quantum indefiniteness on such an interaction. We show that coherent control of the two cavities in an undefined manner allows novel possibilities to manipulate the atomic dynamics on demand which are not achievable in the conventional way. In addition, it is shown that the coherent control of the atom creates highly entangled states of the cavity fields taking a Bell-like or Schrödinger-cat-like state form. Our results are a step forward to understand and harness quantum systems in a coherent control, and open a new research avenue in the study of atom-field interaction exploiting quantum indefiniteness.
我们揭示了关于处于相干叠加态的两能级原子与两个腔之一相互作用研究中的新特性。采用詹姆斯 - 卡明斯模型来描述原子 - 场相互作用，并研究量子不确定性对这种相互作用的影响。我们表明，以不确定的方式对两个腔进行相干控制能够带来按需操纵原子动力学的新可能性，而这是传统方式无法实现的。此外，研究表明对原子的相干控制会产生呈类贝尔态或类薛定谔猫态形式的腔场高度纠缠态。我们的结果朝着在相干控制中理解和利用量子系统迈进了一步，并为利用量子不确定性研究原子 - 场相互作用开辟了一条新的研究途径。
