Fig. 4: Ultrafast uncertainty dynamics in real time.
From: Attosecond quantum uncertainty dynamics and ultrafast squeezed light for quantum communication
a The measured amplitude uncertainty at different delay \(\tau\) times between the three input photons in the FWM nonlinear process (all are on the same scale). b The amplitude uncertainty as evolves in time. The measured amplitude standard deviation “uncertainty” is shown in black dotes connected with a dashed black line (the smoothing is presented in a dashed red line as a guide to the eye)
