Quantum Computing Inc. (“QCi”) (Nasdaq: QUBT) has announced a $750 million oversubscribed private placement of common stock, which brings the total capital raised since November 2024 to $1.64 billion. The offering was led by several large existing shareholders. This financing is intended to accelerate commercialization efforts, strategic acquisitions, and the establishment of volume production capabilities. Following the closing, which is expected on or about October 8, 2025, the company’s total cash position is expected to be approximately $1.55 billion.
Concurrently, QCi has debuted its Quantum Secure Solution at the European Conference on Optical Communication (ECOC) 2025. The solution is a high-dimensional, time-energy-based quantum secure network. It operates at room temperature, is broadband-compatible, and is intended to be a robust alternative to polarization-based approaches for securing sensitive data. The solution leverages time-energy entanglement at telecom wavelengths to provide greater data density and improved scalability.
QCi’s CEO and Chairman of the Board, Dr. Yuping Huang, noted that the funding is believed to be sufficient to execute the company’s business plan through 2028. He stated that the company’s focus now shifts to a transition from a quantum technology innovation company to a quantum hardware manufacturer. The Quantum Secure Solution is a tangible example of this commercialization push, with its debut at ECOC marking a milestone in the company’s plans to make its patented technology mainstream.
This significant capital raise and product launch provide a strong signal of investor confidence in QCi’s vision and technology. The company’s ongoing financial strategy and product development are intended to position it for a future focused on quantum hardware manufacturing and commercial readiness.
