Kerr-Free Three-Wave Mixing in Superconducting Quantum Circuits
2019
Quantum-limited Josephson parametric amplifiers are crucial components in readout chains for circuit quantum electrodynamics. The power handling of state-of-the-art parametric amplifiers is limited by signal-induced Stark shifts. The authors use an innovative circuit element with a Stark-shift-free sweet spot in parameter space to boost the power handling of such an amplifier by an order of magnitude, which is quite promising for the implementation of bilinear Hamiltonians with high dynamic range in quantum information processing.
