Quantum Computing QUBT or QCi’s second-quarter 2026 revenues totaled $5.6 million, up sharply from $61 thousand in the year-ago quarter and $3.7 million in the first quarter of 2026. Revenues were generated across QCi’s integrated portfolio of quantum and photonics technologies, products and services, serving a diverse mix of government, educational and commercial customers.
Growth was primarily driven by sales of photonics products that support the company’s quantum technology roadmap while also addressing existing aerospace, government and industrial applications. QCi exited the quarter with $42.5 million in contract backlog and $1.3 billion in cash, cash equivalents and investments, providing substantial liquidity to support its growth initiatives.
Despite the significant improvement in revenues and a strong liquidity position, profitability remains a key concern as the higher sales base has yet to translate into positive gross or operating results. Operating expenses totaled $21.8 million compared with $10.2 million in the second quarter of 2025, up 114%. This increase was largely due to higher headcount and related payroll costs for research and development efforts, sales and marketing and acquisition-related transaction expenses of $7.3 million. QCi reported a net loss of $11.8 million in the second quarter of 2026, narrowing from a net loss of $36.5 million in the prior-year period.

The company ended the second quarter of 2026 with a strong cash position and no debt, providing flexibility to continue investing behind its technology roadmap and customer opportunities. However, Rigetti’s revenue profile remains tied to the timing of system deliveries and milestone-based development work rather than recurring commercial usage. Operating loss for the quarter was $28.1 million compared with $19.9 million in the prior-year quarter.
