Summary<br />
• Gain ≥ 20 dB for frequencies ≤ 1 GHz<br />
• Cooled to 20 mK, T N is within a factor of 2 of the quantum limit<br />
• Noise temperature 40 times lower than state-of-the-art cooled semiconductor<br />
amplifiers<br />
Future directions<br />
• Implement second-generation axion detector: expected to increase scan<br />
rate by three orders of magnitude<br />
• Post-amplifier for radio-frequency single-electron transistor: should<br />
enable quantum-limited charge amplifier
