We present a protocol for the generation of rare quantum jump trajectories on a digital quantum simulator. Our approach allows to bias open system dynamics with regard to any, even non-linear, function, e.g. it can increase or decrease the likelihood of trajectories with specific emission patterns and correlation properties. We derive the dynamical map of the corresponding biased process. Moreover, we show how the biased open systems dynamics can be implemented on an IBM quantum processor. Using as an example an open two-level system we discuss challenges and current limitations of this approach.
