However, early fault-tolerant devices are not expected to correct arbitrary amounts of error, making the quest for better algorithms an important task.  We concentrate on random product formulas, such as qDrift, and unify this framework with importance sampling, allowing us to sample from arbitrary distributions while controlling both the bias, as well as the statistical fluctuations. We show that the simulation cost can be reduced while achieving the same accuracy by considering the individual simulation cost during the sampling stage. We hope this work to pave the way for tailored qDrift implementations on specific problems and hardware.</span></p><p style=\"font-family:Calibri,sans-serif;font-size:10pt;margin:0;\"><span style=\"font-size:11pt;\"> </span></p><p style=\"font-family:Calibri,sans-serif;font-size:10pt;margin:0;\"><span style=\"font-size:11pt;\">As a bonus, we will also discuss how to compute linear response functions from nuclear scattering experiments using quantum hardware.
