Abstract

In this paper, we introduce analytically the TC-model of two qubits interacting with a coherent cavity field via 2-photon process under the intrinsic dissipation effect. The interaction between the coherent cavity field and the two qubits, which are initially in an uncorrelated state, leads to generate non-locality qubit-qubit correlations. These correlations are investigated by using trace-norm measurement-induced nonlocality and Bures distance entanglement. It is found that the sudden appearance and sudden disappearance of the qubit-qubit entanglement depend not only on the intrinsic noise but also on the initial coherence intensity. The generated non-locality correlations and their stationary values may be controlled by the physical parameters of the intrinsic noise and the initial coherent field state.

通过具有相干场的耗散二量子位系统的2光子共振相互作用产生非局部相关性

摘要

在本文中，我们在固有耗散效应的作用下，通过两光子过程，分析了两个量子位与相干腔场相互作用的TC模型。相干腔场和最初处于不相关状态的两个量子位之间的相互作用导致生成非局部量子位-量子位相关性。通过使用迹线范数测量引起的非局部性和Bures距离纠缠来研究这些相关性。已经发现，量子位-量子位纠缠的突然出现和突然消失不仅取决于固有噪声，而且取决于初始相干强度。可以通过固有噪声和初始相干场状态的物理参数来控制所生成的非局部相关性及其固定值。
