要旨 |
This presentation explores superconducting parametric amplifiers, emphasizing their low-noise performance and capability to achieve quantum-limited noise through parametric interaction. A detailed explanation of the travelling-wave parametric amplifiers (TWPAs) is provided, highlighting its operational principles and advantages. Additionally, the concept of phase matching, essential for attaining high gain across a broad bandwidth, is discussed, demonstrating its significance in enhancing amplifier performance. |
