量子比特间相互作用对同量子谐振腔强耦合的量子比特纠缠性质的影响
Effect of Interaction between Two Qubits on Qubits Entanglement Properties of Ultra-strongly Coupling Quantum Oscillator
摘要
在拉比模型中加入了量子比特之间的相互作用，并用绝热近似的方法求解拉比模型，同时探讨相互作用项对于量子比特纠缠的影响。一个显著的结果是通过选择合适的相互作用参数，可以延长量子比特之间纠缠的时间或提高纠缠度。产生和保持纠缠是量子信息处理的核心。
Abstract
The interaction of the qubits is added in Rabi model and the adiabatic approximation method is used to solve this model. The effect of the entanglement on the interaction parameter is also investigated. A notable result indicates that it can prolong the entanglement time or improve the entanglement degree by using an appropriate interaction parameter. As the generation and preservation of entanglement plays an important role in quantum information processing.
