Roadmap to a superconducting quantum many body simulator

ORAL

Abstract

A superconducting circuit constructed from a repeating pattern of identical unit cells comprising qubits or resonators can be used to simulate a quantum many body system of spins or bosons. While single or few qubit systems have been repeatedly demonstrated in the last few years, the majority of those require tuning each individual qubit frequency through individual control lines. Here, we propose how a larger two-dimensionsal system can be realized with far fewer control lines by focusing on qubit designs that can be uniformly fabricated, with deviation from the design frequency acting as disorder. We examine the operating regimes for such a system and the required fabrication accuracy, as well as readout and control schemes. We discuss how a such a superconducting system could be prepared in non-thermal states in different parts of the many-body spectrum, and consider what observables could be accessed and whether they could be used to test assumptions on entanglement entropy and eigenstate thermalization in 2D systems.
