Abstract
Preparation of correlated fermionic states on a quantum computer for determining a ground state of a correlated fermionic system is provided. In various embodiments, a quantum circuit is provided that comprises a linear chain of qubits and a plurality of matchgates arranged in layers. Each matchgate is configured to perform a two-qubit rotation on neighboring qubits within the linear chain. An initial state is provided for each qubit in the linear chain, The quantum circuit is applied to the initial values, thereby preparing an ansastz on the linear chain of qubits, the ansatz corresponding to a fermionic state.
