AI总结:

该研究在 Markovian 玻色热库模型下分析电容耦合多能级 transmon 电路,通过改变耦合强度并考察零资源初始态,确定实现最大纠缠生成能力的最优可分态。

摘要:

我们在 Markovian 极限内分析了被玻色热库包围的电容耦合多能级 transmon 电路的量子资源生成。在实际中,超导电路元件通常是更大电路的一部分,该电路由许多其他线性电路元件构成,并假定这些元件连同其环境由热库模拟。我们针对制备在零资源初始态上的系统,研究资源生成对耦合强度变化的响应。我们特别关注作为资源的纠缠和量子相干性。我们量化了耦合 transmon qutrit 的纠缠生成能力,同时考虑系统能够生成的最大纠缠,以及系统能够维持显著纠缠的时间尺度。我们识别出可带来最大纠缠生成能力的最优初始可分态。

英文摘要:

We analyze the quantum resource generation of capacitively-coupled multilevel transmon circuits surrounded by bosonic baths, within the Markovian limit. In practice, the superconducting circuit elements are usually part of a larger circuit, constructed with many other linear circuit elements, which along with their environment is assumed to be mimicked by the baths. We study the response to variation of the coupling strength of resource generation for thee system prepared in zero-resource initial states. We focus, in particular, on entanglement and quantum coherence as resources. We quantify the entanglement generation power of coupled transmon qutrits, taking into account the maximum entanglement the system can generate and the time-scale over which the system can sustain a significant entanglement. We identify the optimal initial separable states leading to maximum entanglement generating power.
