Amplification and squeezing of quantum noise with a tunable Josephson metamaterial

1 min read

Demonstrates a tunable Josephson metamaterial amplifier operating from 4 to 8 GHz. In phase-sensitive operation it added less than half a noise quantum and squeezed vacuum fluctuations by 10 dB.

Key Results

  • 4–8 GHz tunable operating range
  • Less than one-half quantum of added noise in phase-sensitive operation
  • 10 dB squeezing of quantum fluctuations
