A system and method for initializing and optimizing a variational quantum circuit on a hybrid quantum-classical computer, comprising a set of gates and a set of initial parameters representing a model of a physical system. A quantum circuit is generated comprising a set of smaller contiguous subcomponents which can be independently optimized to minimize a property of the physical system, such as ground state energy or the absorption spectrum of a molecule. At least one entangling gate is introduced between at least two circuit subcomponents. The initial parameters of the circuit components may be set according to values obtained from a parameter library. Once the initial parameters are set, the circuit components of the quantum computer proceed to optimization, which is independent for each subcomponent of the system. The optimization method may also include the use of a variational quantum eigensolver (VQE).
