论文摘要
我们研究光子/声子束和抗挑战对具有平衡/不平衡增益和损失的耦合PT对称系统的量子纠缠动力学的重要性。我们建议一种混合机电系统，以通过超导转导的转导矩形Qubit在Coplanar-WaveGuide（CPW）微波腔（CPW）微波腔与纳米力学谐振器（NAMR）之间实现强大而可调的耦合。杂种机电系统由一个非热汉密尔顿人组成，具有平衡/不平衡的增益和损失。量子纠缠与 - 对称系统之间的相互作用也得到了彻底研究。我们在数字运算符，光子/声音抗启动和纠缠之间建立连接。已经观察到，相对光子/声子数在量子纠缠动力学中起关键作用。此外，我们研究量子纠缠可以通过定义光子/声子抗挑战来表征。光子/声子抗启动强烈取决于初始挤压状态以及平衡/不平衡的增益和系统损失的速率。
We study the significance of Photon/Phonons bunching and antibunching on the dynamics of the quantum entanglement in the presence of coupled PT-symmetry systems with balanced/unbalanced gain and loss. We suggest a hybrid electromechanical system to realize a strong and tunable coupling between a Coplanar-Waveguide (CPW) microwave cavity and a nanomechanical resonator (NAMR) via a superconducting Transmon qubit. The hybrid electromechanical system consists of a non-hermitian Hamiltonian with balanced/unbalanced gain and loss. The interplay between the quantum entanglement and the -symmetry systems is also thoroughly investigated. We frame a connection between Number operators, Photon/Phonons antibunching, and entanglement. It has been observed that the relative Photon/Phonons numbers play a key role in quantum entanglement dynamics. Furthermore, we study that quantum entanglement can be characterized by defining a Photon/Phonons antibunching. The Photon/Phonons antibunching is strongly dependent on the initial squeezed state and the rate of balanced/unbalanced gain and loss of the system.
