Abstract:

Density functional theory (DFT) has become a central aspect of quantum chemistry and provides the mainstay of chemical calculations. The advantage of DFT methods lies in their relatively inexpensive computational cost and their dealing with an experimentally tangible quantity, i.e. the density. The chief drawback is its lack of well-defined path from approximation to exactitude. Consequently many models and approaches have emerged, and been enthusiastically advocated, often with little more justification than "it works". This thesis begins with an overview of traditional quantum chemical theor

Abstract:

Since its introduction one decade ago, the quantum algorithm for chemistry has been among the most anticipated applications of quantum computers. However, as the age of industrial quantum technology dawns, so has the realization that even “polynomial” resource overheads are often prohibitive. There remains a large gap between the capabilities of existing hardware and the resources required to quantum compute classically intractable problems in chemistry. The primary contribution of this dissertation is to take meaningful steps towards reducing the costs of three approaches to quantum computing

Abstract:

The design of new materials and chemicals derived entirely from computation has long been a goal of computational chemistry, and the governing equation whose solution would permit this dream is known. Unfortunately, the exact solution to this equation has been far too expensive and clever approximations fail in critical situations. Quantum computers offer a novel solution to this problem. In this work, we develop not only new algorithms to use quantum computers to study hard problems in chemistry, but also explore how such algorithms can help us to better understand and improve our tradition

Abstract:

This thesis describes the development of a scheme for applying wavefunction-based quantum chemistry techniques to crystalline solids: the hierarchical method. The hierarchical method was first proposed by Manby, Gillan and Alfe [1] for cubic crystals. The contribution of electron correlation to the cohesive energy of a crystal is found from calculations on finite clusters of atoms. These clusters are chosen to mimic the structure of the crystal and the edge-effects are subtracted using the hierarchical equation. The quantum chemistry techniques used offer advantages in accuracy over existing s

Abstract:

The evaluation of molecular integrals is a vital but computationally expensive part of electronic structure calculations. This computational expense is particularly problematic for the explicitly correlated methods, in which complicated and numerous integrals over more than two-electrons must be evaluated. The successful R12/F12 methods overcome this difficulty by decomposition of these many-electron integrals by means of approximate resolutions of the identity (RIs). To obtain accurate results with this approach, however, requires large auxiliary basis sets with high angular momentum function

The simulation of chemical reactions, specifically ultrafast photochemical reactions is notoriously difficult. Using classical computers, the computational cost to simulate these interactions scales exponentially. By using a controllable quantum device, the quantum hardware cost scaling is instead linear. With this method, it is possible to directly implement the Hamiltonian evolution of a particular quantum system of interest. This approach is known as analog quantum simulation. This thesis describes the experimental implementation of an analog quantum simulation using a trapped ion system. U
