Driven dissipative quantum many-body systems hold a variety of interesting phenomena like dissipative quantum phase transitions and non-equilibrium steady states. Typically, the full theoretical understanding of these phenomena is hindered by complex dynamics in large Hilbert spaces. Within this context, quantum simulation is a promising alternative bridging the gap between theory and experiment. Our project aims at finding efficient ways to simulate dissipative and driven many-body systems on NISQ devices. To this end, we make use of a software package provided by HQS Quantum Simulations capable of simulating complex open quantum systems. The key idea of this approach is to view quantum hardware itself as being a driven dissipative many-body system. More specifically, we utilize the noise on the hardware to engineer the required decoherence processes for the system under study. Building up on recent theoretical advances we show how to reduce the resources needed for these simulations.
