[quant-ph] 24 Jul 2016Quantum computing with atomic qubits andRydberg interactions: Progress and challengesM. SaffmanDepartment of Physics, University of Wisconsin-Madison, 1150 UniversityAvenue, Madison, Wisconsin, 53706, present a review of Quantum computation with neutral atomqubits. After an overview of architectural options and approaches to preparinglarge qubit arrays we examine Rydberg mediated gate protocols and fidelity fortwo- and multi-qubit interactions. Quantum simulation andRydberg dressingare alternatives to circuit based Quantum computing for exploring many bodyquantum dynamics. We review the properties of the dressing interaction andprovide a quantitative figure of merit for the complexity of the coherent dynamicsthat can be accessed with dressing. We conclude with a summary of the currentstatus and an outlook for future to:J. Phys. BQuantum computing with atomic qubits and Rydberg interactions: Progress and challenges21.
