Abstract: Precise and accurate measurements of the polarization of the Cosmic Microwave Background (CMB) holds great promise for several fundamental physics targets, including a measurement of the neutrino mass scale from cosmology, or constraints or possible detection of a background of primordial gravitational waves from inflation. The extraction of the gravitational lensing signal ('CMB lensing and delensing') plays a key role towards these targets. I will review briefly the most recent results in this area from Planck and ACT, and discuss the most recent developments in the techniques and their prospects for Simons Observatory and CMB-S4.
