There is an increasing interest to develop quantum circuits capable of performing many-body quantum simulation motivated by their scaling advantages against classical devices. We present an analysis of the performance of the unitary coupled cluster method for the 6Li nucleus in the shell model framework. Our work consists of several tests aimed to establish proper criteria to improve its performance. By isolating the main aspects of the UCC ansatz, we are able to understand their effect on the simulation. Consequently, we identify different ways to optimise the 6Li simulation by reducing the operators used and choosing efficient Trotter number and reference state.
