Scaling up a superconducting qubit lattice with parametric gates

 · Invited

Abstract

Scaling up superconducting qubit systems presents a number of challenges in various domains including: control systems, fabrication, packaging, signal delivery, and software automation. I will report on initial efforts at Rigetti toward scaling up the 8Q platform toward larger, more connected lattices of qubits and how we address some of these challenges. In particular, I will examine the performance of parametric gates in these lattices, and touch on operational measures of crosstalk, such as dependence of simultaneous benchmarking on distance (in real space and frequency space) between qubit subsystems.
