标题： Inter-qubit interaction mediated by collective modes in a linear array of three-dimensional cavities

摘要： 一种乐高式构造套装的设计已被开发，该套装允许组装不同的三维(3D)空腔和量子比特的线性阵列，用于电路量子电动力学(cQED)实验。 通过使用高频结构模拟器(HFSS)，对嵌入在空腔阵列中的量子比特-三维空腔阵列的电磁特性进行了研究。 提出了一种估算嵌入在空腔阵列不同空腔中的量子比特之间量子比特耦合强度的技术，该技术结合了系统的哈密顿描述与简单的HFSS仿真。 通过使用该技术获得的量子比特间耦合强度与直接仿真得到的结果之间的一致性，证明了该方法适用于更复杂的量子比特-空腔阵列，在这些阵列中有限元电磁仿真器的使用受到限制。 显示英文摘要

摘要： A design of LEGO-like construction set that allows assembling of different linear arrays of three-dimensional (3D) cavities and qubits for circuit quantum electrodynamics (cQED) experiments has been developed. A study of electromagnetic properties of qubit-3D cavity arrays has been done by using high frequency structure simulator (HFSS). A technique for estimation of inter-qubit coupling strength between qubits embedded in different cavities of cavity array, which combines Hamiltonian description of the system with simple HFSS simulations, has been proposed. A good agreement between inter-qubit coupling strengths, which were obtained by using this technique and directly from simulation, demonstrates the suitability of the method for more complex qubit-cavity arrays where usage of finite-element electromagnetic simulators is limited.
