Quantum simulations offer a promising path toward understanding fermionic quantum many-body systems without the limitations of exponential scaling. In this talk, I will present ongoing efforts to simulate various quantum algorithms designed to address nuclear systems within the shell model framework. I will begin by discussing hybrid variational algorithms, highlighting our estimates of the quantum resources required for a range of nuclear systems [1,2]. I will then explore predictions for nuclear entanglement properties [3] and how these can be leveraged in entanglement forging applications [4]. Finally, I will introduce our recent proposal for an adiabatic quantum algorithm tailored to solving the nuclear shell model [5], including a quasi-boson encoding that provides very accurate results for ground states [6].
