ROI Calculation Logic

In quantum computer manufacturing, wiring-related costs are estimated to account for approximately 30% of total costs. If this technology reduces wiring by an average of 60%, it could cut manufacturing costs by about 18% (30% × 60%). For an annual production of 10 units, with a manufacturing cost of ~$33.5M (AI est.) per unit, the potential reduction is (~$33.5M × 0.18) × 10 units = ~$60M (AI est.) annually. Including reduced maintenance and cooling costs during operation, an estimated annual cost reduction of ~$10M (AI est.) is expected.
