Fig. 2: Experimental measured ZPF (red circles) versus the antisqueezing strength ξ, demonstrating exponentially enhanced ZPF of the oscillator by the antisqueezing effect.

The theoretical expectation is shown in the dashed line. The inset plot shows the standard deviation of ZPF for each data point. The measured Wigner functions of two squeezed vacuum states are shown in the right side.
