论文摘要
我们研究了两个两级量子位与腔中单个模式量子场的相互作用，而无需旋转波近似，并考虑量子位可以彼此任意距离。我们证明存在辐射诱导的原子之间的相互作用电位。我们通过数值研究了系统的属性，并构建了简单的分析近似。结果表明，可观察到的特性在很大程度上取决于强耦合方案中Qubit之间的距离。这允许人们执行量子器的量子控制，可以利用量子信息的记录和传输。
We investigate the interaction of two two-level qubits with a single mode quantum field in a cavity without rotating wave approximation and considering that qubits can be located at an arbitrary distance from each other. We demonstrate that there exists a radiation induced interaction potential between atoms. We studied the properties of the system numerically and in addition constructed a simple analytical approximation. It is shown that the observable characteristics are substantially dependent on the distance between the qubits in the strong coupling regime. This allows one to perform the quantum control of the qubits, which can be exploited for the recording and transmission of quantum information.
