Design and characterization of a multi-qubit circuit for quantum simulations

ORAL

Abstract

Superconducting qubits, due to remarkable progress in coherence times, have recently realized a variety of quantum simulation experiments. These simulations, which promise to shed light on open questions in fields ranging from quantum chemistry to quantum chromodynamics, have largely been performed with either a single qubit or a few coupled qubits. Implementing more sophisticated simulations requires scaling up the number of qubits on a single chip.~ Additionally, the recent development of a broadband near-quantum-limited amplifier offers the possibility to simultaneously read out the state of multiple qubits on a single device. We present initial progress on the design, fabrication, and characterization of such a multi-qubit cQED circuit, with a focus towards near-term quantum simulation applications.
