Abstract

We have designed, fabricated, and measured an advanced quantum annealing processor comprised of 25 capacitively-shunted flux qubits (CSFQs) connected by 40 rf-SQUID tunable couplers. Each CSFQ features state-of-the-art persistent current readout (https://arxiv.org/abs/2006.10817). Over 200 dedicated bias lines enable unprecedented control over annealing schedules. To achieve the required scale and signal density while maintaining high coherence, we leverage MIT Lincoln Laboratory’s 3-tier stack fabrication and 3D integration process. We detail a novel design approach where the control and readout circuitry are routed through multiple chip tiers to create a modular architecture, and discuss how the device opens new horizons for both algorithm and hardware prototyping.
