Dissipative Stabilization of Squeezing Beyond 3 dB in a Microwave Mode
Dissipative Stabilization of Squeezing Beyond 3 dB in a Microwave Mode
While a propagating state of light can be generated with arbitrary squeezing by pumping a parametric resonator, the intra-resonator state is limited to 3 dB of squeezing. Here, we implement a reservoir engineering method to surpass this limit using superconducting circuits. Two-tone pumping of a three-wave-mixing element implements an effective …
