  • Squeezed states are key resources in quantum technologies, but generating high squeezing usually requires strong nonlinearity. Here, the authors propose and demonstrate a displacement-enhanced squeezing approach that uses weak Kerr nonlinearity and off-resonant driving to generate and amplify squeezing inside a superconducting microwave cavity, reaching 14.6 dB of intracavity squeezing.
