Abstract
Systems and methods are provided for performing noise-resilient quantum operations. A set of control signals are applied to a system to provide a first Hamiltonian for the system. The system includes an array of physical qubits and a plurality of coupling mechanisms configured such that each pair of neighboring physical qubits within the array is coupled by an associated coupling mechanism. The first Hamiltonian represents, for each coupling mechanism, a coupling strength between zero and a maximum value. An adiabatic interpolation of the Hamiltonian of the system from the first Hamiltonian to a second Hamiltonian is performed. The second Hamiltonian represents, for at least one of the plurality of coupling mechanisms, a coupling strength different from that of the first Hamiltonian.
