Silicon is not one of the leading modalities for quantum computers, but it has progressed a lot in the past ~2-3 years. Here are a few key advancements that have happened as of late: - Intel can now do 2D which means a Surface code can be run on these devices: https://arxiv.org/abs/2412.14918 - HRL can now do 2D as well: https://arxiv.org/abs/2502.08861 - They are solving the wiring problem: https://www.nature.com/articles/s41565-023-01491-3 - Their interconnects are high fidelity: https://www.nature.com/articles/s41586-025-09827-w
