Quantum Computing Inc: Revenue Jumps More Than 90-Fold To $5.6 Million As Backlog Reaches $42.5 Million

Quantum Computing Inc. generated $5.6 million in Q2 2026 revenue compared with just $61,000 a year earlier, increasing quarterly revenue by more than 90 times as the company’s photonics, semiconductor-manufacturing, and quantum-computing businesses begin producing a larger commercial contribution.

Revenue also increased sequentially from $3.7 million in Q1, while contract backlog reached approximately $42.5 million as of June 30. The backlog was roughly 7.6 times Q2 revenue, providing a substantially larger base of contracted business than the amount recognized during the quarter.

QCi said revenue came from its integrated portfolio of quantum and photonics technologies, products, and services serving government, educational, and commercial customers. Photonics products serving aerospace, government and industrial applications were the primary revenue driver.

Commercial activity expanded across several areas during the quarter. QCi sold, delivered and installed a Dirac-3 quantum optimization machine at a leading global consulting firm, where it will be used with enterprise customers for applications including portfolio optimization.

The company also brought its NeuraWave photonic reservoir computing platform to deployment readiness. NeuraWave combines photonic and digital computing for AI inference and signal processing and is being targeted at applications spanning defense, telecommunications, robotics, healthcare and industrial monitoring.
