In my talk I will present recent advances in designing tailor-made states of light with optimal properties in scattering across highly disordered media. First, I will discuss how the concept of Fisher information allows us to distill  from the measurable scattering matrix of a system the unique state of light, which delivers the maximum amount of information about a desired system parameter of interest to an external observer [1]. In a second part, I will discuss so-called "scattering-invariant modes”; these light fields have the unique property that they are transmitted across a disordered medium with the same output profile as when travelling through free space [2]. Both of these concepts were recently implemented together with the group of Allard Mosk in Utrecht using optical wave-front shaping tools.
