Abstract

The possibility of calculating the electronic structure of atomic systems using a noisy quantum computer is investigated. For this purpose, the ground state energy of the moscovium atom is calculated using the Qiskit simulator and the Variational Quantum Eigensolver algorithm with the dUCC-SD ansatz. The algorithm parameters are optimized utilizing the Adam procedure. The robustness of the algorithm to noise is studied in the framework of a two-qubit phase damping noise.
