Circuit design for multi-body interactions in superconducting quantum annealing systems with applications to a scalable architecture

Abstract

Quantum computing: Superconducting multi-qubit interaction circuits A new method to build devices which implement interactions between more than two qubits in quantum annealing systems similar to those produced by D-Wave Systems has been proposed by a collaboration from UCL, Durham University, and the University of Oxford led by Paul Warburton. Such interactions occur naturally in many real world optimization problems. They demonstrate that constructing these circuits is experimentally feasible in the near term, and discuss how additional degrees of freedom included in their technique could help solve problems more efficiently. This new coupler design opens up a wide array of new architectural possibilities for these devices, as well as new ways in which they could solve problems, potentially leading to a new generation of more efficient quantum annealers.
