Data as of May 28, 2026.Foolish TakeExamining the revenue trends between IonQ and Quantum Computing Inc., which refers to itself as QCi, shows a stark contrast, and provides meaningful insights to investors. Not only is IonQ’s sales consistently larger than QCi’s, its revenue growth rate is spectacular.For example, IonQ reported record revenue of $64.7 million in the first quarter, representing jaw-dropping 755% year-over-year growth. This indicates the company’s ion-based quantum computing technology is capturing customers.Meanwhile, QCi’s sales trend shows anemic and inconsistent revenue, revealing its photonic technology hasn’t been able to gain traction with customers. That finally seemed to change in Q1 with sales of $3.7 million compared to just $39,000 in the previous year. However, that dramatic boost came from its acquisition of NuCrypt and Luminar Semiconductor.Given what the revenue numbers between these two companies reveal, IonQ looks like a solid business to invest in for those who want exposure to the quantum computing sector. Its technology is winning customers, as its strong growth rate and consistency in rising revenue over recent quarters indicates.QCi has not proven its technology can generate meaningful sales, and its Q1 year-over-year increase was due to acquisitions, not customer growth. This trend is concerning, unless the acquired businesses can help to ignite sales.Read NextMay 28, 2026 •By Sean WilliamsQuantum Computing Stocks IonQ, Rigetti Computing, and D-Wave Quantum Are Sending Shockwaves Through Wall Street With This $931 Million WarningMay 26, 2026 •By Robert IzquierdoD-Wave Quantum vs. IonQ: Which Quantum Computing Stock Is a Better Buy in 2026?May 25, 2026 •By Geoffrey SeilerThe U.S.
