Figure 3: Schematic of the dispersive squeezing protocol outlined in the text.
From: Qubit-flip-induced cavity mode squeezing in the strong dispersive regime of the quantum Rabi model

Heavy dashed arrows represent qubit flips, while solid lines indicate time evolution under the corresponding oscillator Hamiltonian. The ellipses illustrate the state of the field before and after each qubit flip. One full cycle plus the first step of a second is shown here.
