    "abstract": "Modern Quantum optics largely remains quasi-stationary, far from intrinsic optical field timescales. Ultrafast quantum optics seeks to generate, shape, and measure quantum states of light on femtosecond and attosecond timescales. Here we introduce a quantum light field squeezer (QLFS) that enables the generation and attosecond control of ultrafast broadband squeezed light. Using degenerate four-wave mixing in a quasi-collinear focusing geometry, our approach overcomes conventional broadband phase-matching limits, producing intensity- and phase-squeezed states directly from few-cycle laser pulses. Our ultrafast quantum optical metrology reveals a time-dependent squeezing distribution across individual half-cycles of the electric field. Incorporating this time-dependent squeezing into strong-field simulations shows that the temporal redistribution of quantum uncertainty reshapes the high-harmonic emission. Moreover, by tuning the relative pulse delay and phase-matching angle, we achieve attosecond precision in controlling the squeezing characteristics by visualizing inferred effective Wigner representations of the quantum light field. Beyond characterization, we demonstrate that the quantum light-induced tunneling-current noise is sensitive to the nonclassical intensity-noise statistics of the driving squeezed light, with sub-femtosecond control. Together, these results extend the generation, control, and effective phase-space representation of squeezed light into the ultrafast and attosecond regime, opening new avenues for quantum optics in strong-field and solid-state systems.",
