High-density I/O for next-generation quantum annealing: Part 1—Cryogenic wiring

ORAL

Abstract

As superconducting quantum processors continue to scale up in size, it becomes increasingly challenging to route the required number of control lines through a dilution refrigerator to the qubit chip. In this presentation, we will discuss our efforts to develop high-density fridge wiring for use in next-generation quantum annealers. Our wiring solution is based on flexible multi-channel cables with a stripline geometry, designed to achieve low crosstalk and moderate bandwidth. We will describe the electrical performance of these cables, as well as other design considerations such as thermal management.
