The recently developed Projective Quantum Eigensolver (PQE) offers an elegantprocedure to evaluate the ground state energies of molecular systems on quantumcomputers. However, the noise in available quantum hardware can result insignificant errors in computed outcomes, limiting the realization of quantumadvantage. Although PQE comes equipped with some degree of inherent noiseresilience, any practical implementation with apposite accuracy would requireadditional routines to suppress the errors further. In this work, we propose away to enhance the efficiency of PQE by developing an optimal framework forintroducing Zero Noise Extrapolation (ZNE) in the nonlinear iterative procedurethat outlines the PQE; leading to the formulation of ZNE-PQE. For this method,we perform a detailed analysis of how various components involved in it affectthe accuracy and efficiency of the reciprocated energy convergence trajectory.Moreover, we investigate the reasons behind the improvements observed inZNE-PQE over conventional PQE by performing a comparative analysis of theirresidue norm landscape. This approach is expected to facilitate practicalapplications of quantum computing in fields related to molecular sciences,where it is essential to determine molecular energies accurately.
