Analog quantum simulation using superconducting qubits — •Stefan Oleschko1,2, Oscar Gargiulo1,2, Maximilian Zanner1,2, Aleksei Sharafiev1,2, and Gerhard Kirchmair1,21Institute for Quantum Optics and Quantum Information, A-6020 Innsbruck, Austria — 2Institute for Experimental Physics, University of Innsbruck, A-6020 Innsbruck, Austria

In this talk I want to present the research activities of the Superconducting Quantum circuits group at the Institute for Quantum Optics and Quantum Information in Innsbruck. I will show how we want to use 3D circuit QED architectures to realize a platform for quantum many body simulations of dipolar XY models on 2D lattices using state of the art circuit QED technology. The central idea is to exploit the naturally occurring dipolar interactions between 3D superconducting qubits to simulate models of interacting quantum spins. The ability to arrange the qubits in essentially arbitrary geometries allows us to design spin models with more than nearest-neighbor interaction in various geometries. We will be able to investigate quantum phenomena in 2D where qualitatively new features emerge and existing numerical and analytical approaches reach their limitations.
