US Patent 10311369 Quantum gates via multi-step adiabatic drag

Systems and methods are provided for performing a quantum gate operation. The system includes a first physical qubit, and a second physical qubit operatively coupled to the first physical qubit via a coupling mechanism. The first physical qubit, the second physical qubit, and the coupling mechanism form a logical qubit. At least one control mechanism is configured to provide a control signal to one of the first physical qubit, the second physical qubit, and the coupling mechanism as to adjust a Hamiltonian of the logical qubit.
