What quantum companies actually sell: revenue masks the true state of commercialization
続きを読む: What quantum companies actually sell: revenue masks the true state of commercializationQuantum companies’ revenues are growing, but their sources vary widely — hardware sales, government contracts, PoCs, cloud usage, quantum sensing, and more. By examining major firms’ revenue structures, we can better gauge the current state of quantum computer commercialization.
