Description
In the talk I will review recent work to compute multi-loop amplitudes through numerical unitarity. I will highlight the appearance of subleading poles starting at two loops and show a systematic way to handle them in a numerical framework. Applications to two-loop four-gluon amplitudes will be discussed.
