Figure 4: Degree of squeezing obtained after one cycle of the protocol in the ideal dispersive case (open squares), as a function of the coupling strength g/ω.
From: Qubit-flip-induced cavity mode squeezing in the strong dispersive regime of the quantum Rabi model

For comparison the squeezing present in the ground state
is also shown (solid). Other physical parameters include: Δ/ω = 2, Ω/ω = 1 + Δ/ω.
