Widely tunable parametric amplifier based on a superconducting quantum interference device array resonator

Year: 2007

Type: article

Abstract: The authors create a Josephson parametric amplifier from a transmission line resonator whose inner conductor is made from a series of superconducting quantum interference device (SQUID) array. By changing the magnetic flux through the SQUID loops, they are able to adjust the circuit’s resonance frequency and the center of the amplified band between 4 and 7.8GHz. They observe that the amplifier has gains as large as 28dB and infers that it adds less than twice the input vacuum noise.
