| Abstract: | Devices based on superconducting-qubits coupled through a microwave cavity show certain promise for quantum information processing. The development of an experimentally feasible approach to achieve high fidelity operation in this scalable system is very important. We introduce here a feasible scheme that can implement a universal set of quantum gates and produce multiqubit entanglement as well as construct quantum error-correcting codes based on the same set of fanlt-tolerant geometric quantum operations. |
