论文摘要
在构建量子信息处理设备方面，延长量子线相干时间是至关重要的任务。在电路QED的三维空腔实现中，由于减少了与光子发射相关的损失，超导量子位的相干性得到了显着改善。改善连贯性的下一个前沿包括减轻超导准颗粒的不良反应。在这些讲座中，我们回顾了准粒子动力学的基础知识，它们与量子的自由度的相互作用，对量子放松率的贡献以及控制其效果的方法。
Extending the qubit coherence times is a crucial task in building quantum information processing devices. In the three-dimensional cavity implementations of circuit QED, the coherence of superconducting qubits was improved dramatically due to cutting the losses associated with the photon emission. Next frontier in improving the coherence includes the mitigation of the adverse effects of superconducting quasiparticles. In these lectures, we review the basics of the quasiparticles dynamics, their interaction with the qubit degree of freedom, their contribution to the qubit relaxation rates, and approaches to control their effect.
