Why does Microsoft need multiple quantum computers for molecular simulation?

Microsoft's roadmap includes developing not just one quantum computer but thousands because of the need for high-throughput molecular simulation. Rather than simulating one molecule at a time, they aim to simultaneously simulate thousands of different molecules in parallel to efficiently discover materials with desired properties. This approach would revolutionize research in critical areas like carbon capture, hydrogen fixation for fertilizers, non-PFAS coolants, and better superconductors. Traditional experimental screening is costly, slow, and energy-consuming, making quantum simulation a more efficient alternative for identifying promising compounds.
