I have published a paper in the archives with the title &#34;<a href="https://arxiv.org/abs/2111.02448" rel="noopener noreferrer" target="_blank">[2111.02448] Prescreening method for Variational Quantum State Eigensolver (arxiv.org)</a>&#34; This paper shows that the accuracy of Variational Quantum State Eigensolver (VQSE) can be improved by preprocessing. The preprocessing is done in SSVQE and targets the ground state, triplet state, singlet state, and two-electron excited state. As a result, it was found that the accuracy of all the states including the ground state was improved for molecular hydrogen, while the accuracy of lithium-hydrogen was decreased because each state was packed.

Notice of publication of paper: Preprocessing in VQSE.
