  1. In a pure gauge 3 × 3 OBC system, the four dynamical gauge fields can be simulated with the specified total number of qubits. Additionally, we quantify the total count of CNOT gates and the CNOT depth, representing the layers of CNOT gates in the circuit. The rightmost column displays the total number of parameters in the variational Ansatz.
