Circuit schematic for the generation of squeezed propagating microwave states. In case (a) JPA2 is in the vacuum state (the respective microwave pump is switched off) is depicted. In case (b) both JPAs are operated such that symmetric TMS states are generated at the outputs of the hybrid ring. State detection, in both cases, is realized with the dual-path detector23,28 based on cross-correlation quadrature measurements. For finite-time correlation measurements, we introduce a time delay τ in one of the paths.
