Quantum chemistry is regarded to be one of the first disciplines that will berevolutionized by quantum computing. Although universal quantum computers ofpractical scale may be years away, various approaches are currently beingpursued to solve quantum chemistry problems on near-term gate-based quantumcomputers and quantum annealers by developing the appropriate algorithm andsoftware base. This work implements the general Quantum Annealer Eigensolver(QAE) algorithm to solve the molecular electronic Hamiltonianeigenvalue-eigenvector problem on a D-Wave 2000Q quantum annealer. The approachis based on the matrix formulation, efficiently uses qubit resources based on apower-of-two encoding scheme and is hardware-dominant relying on only oneclassically optimized parameter. We demonstrate the use of D-Wave hardware forobtaining ground and electronically excited states across a variety of smallmolecular systems. This approach can be adapted for use by a vast majority ofelectronic structure methods currently implemented in conventionalquantum-chemical packages. The results of this work will encourage furtherdevelopment of software such as qbsolv which has promising applications inemerging quantum information processing hardware and is able to address largeand complex optimization problems intractable for classical computers.
