To commercialize quantum computing, manufacturers need high-quality superconducting materials for microchips, but they also require a reliable, sustainable nanofabrication process. Tantalum is a corrosion-resistant metal that meets the first criterion but not the second. That's because it has to be deposited on a substrate at temperatures that typically exceed 400°C (752°F)—too hot for many semiconductor foundries' current tools.
