Fluctuations. This inset shows fluctuations ${\left(\Delta {\widehat{q}}_1\right)}_{\mathrm{c}}$ (dashed line) and ${\left(\Delta {\widehat{q}}_1\right)}_{\mathrm{s}}$ (thick solid line) (a), and ${\left(\Delta {\widehat{p}}_1\right)}_{\mathrm{c}}$ (dashed line) and ${\left(\Delta {\widehat{p}}_1\right)}_{\mathrm{s}}$ (thick solid line) (b), and uncertainty product ${\left(\Delta {\widehat{q}}_1\right)}_{\mathrm{c}}{\left(\Delta {\widehat{p}}_1\right)}_{\mathrm{c}}$ (dashed line) and ${\left(\Delta {\widehat{q}}_1\right)}_{\mathrm{s}}{\left(\Delta {\widehat{p}}_1\right)}_{\mathrm{s}}$ (thick solid line) (c) as a function of t where n₁=n₂=0, $\hslash =1$, R₀ = R₁ = R₂ = 0.1, L₀ = L₁ = L₂ = 1, C₁ = 1, and C₂ = 1.2. The values of squeezing parameters for the DSN are r₁ = 0.1, r₂ = 0.3, ϕ₁ = 1.2, and ϕ₂ = 0.6.
