Quantum Computing Inc. Down 11.4% After Oversubscribed Funding and Photonic Tech Debut: What's Changed

Quantum Computing Inc. has raised $499.73 million in an oversubscribed private placement and debuted its Quantum Secure Solution at the European Conference on Optical Communication 2025. The company is expanding into commercial and government markets with early demand for its quantum computing systems and a new photonic chip foundry expected to contribute to future revenues. However, the company's revenue remains low, and heavy losses continue, leading to concerns about its financials and corporate stability.
