This dissertation studies quantum computing in the context of quantum many-body systems and size-limited quantum computers. First, we discuss the main properties of ground states of local gapped Hamiltonians from a quantum computing perspective. We then consider several quantum algorithms for preparing relevant quantum many-body states on a quantum computer. Finally, we explore approaches to hybrid quantum-classical algorithms when only quantum computers constrained in the number of qubits are available.
