Linear-response functions of molecules on a quantum computer: Charge and spin responses and optical absorption
We propose a scheme for the construction of linear-response functions of an interacting electronic system via quantum phase estimation and statistical sampling on a quantum computer. By using the unitary decomposition of electronic operators for avoiding the difficulty due to their nonunitarity, we...
