Light fields are now routinely structured across many degrees of freedom (i.e., spatial, temporal, and spectral), enabling unprecedented control over their classical properties. Although light's quantum properties limit important applications such as communications, imaging, and spectroscopy, an approach to shape the quantum statistical properties of light, such as correlations and noise, is missing. Here, we show that combining wavefront shaping with optical nonlinearity offers an unprecedented degree of control over the classical and quantum properties of light simultaneously. In our experimental demonstration, we combine spatial light modulation with the nonlinear dynamics offered by a multimode fiber to focus a region of high intensity, yet low noise, at the output of the fiber. The fiber output has intensity noise 20 times lower than what is achievable by linear means, and is at the quantum shot-noise level despite a highly noisy input.
