论文摘要
在电路量子电动力学领域调制和频率翻译的重要设备是智商混合器,这是一种模拟组件,为实现最佳性能而需要进行校准。在本文中,我们介绍了最初为无线通信应用开发的技术,以校准上转换和下调混音器。与可控载体频率偏移的Kalman过滤器校准了两个混合器,而无需将它们从嵌入测量基础架构中删除。这些技术可以嵌入室温控制电子设备中,随着电路QED设备的尺寸和复杂性的增长,它们会发现广泛使用。
An important device for modulation and frequency translation in the field of circuit quantum electrodynamics is the IQ mixer, an analog component for which calibration is necessary to achieve optimal performance. In this paper, we introduce techniques originally developed for wireless communication applications to calibrate upconversion and downconversion mixers. A Kalman filter together with a controllable carrier frequency offset calibrates both mixers without removing them from the embedding measurement infrastructure. These techniques can be embedded into room temperature control electronics and they will find widespread use as circuit QED devices continue to grow in size and complexity.
