The system will serve as the core of a new secure testbed — an isolated, quantum-secured infrastructure being set up within the bank’s recently launched Cybersecurity Quantum Optics Lab.

This installation will be used to test and validate next-generation encryption and authentication tools, including quantum key distribution, quantum random number generation and quantum authentication protocols.

The company’s solution transmits entangled photons using time-frequency encoding at telecom wavelengths, enabling seamless integration with current fiber-optic networks.

Housed in compact, rack-mounted enclosures, the platform is designed for easy scalability and operational stability.

The same system can deliver both secure encryption and patented authentication protocols, giving enterprises a unified defense framework.

“This order represents a pivotal commercial validation of QCi’s quantum photonics and hardware capabilities,” said Yong Meng Sua, chief technology officer at Quantum Computing.

Pouya Dianat, Quantum Computing’s chief revenue officer, added that the partnership underscores how QCi’s innovations are finding real-world use in critical infrastructure sectors like finance.

The purchase includes not only the quantum hardware but also professional services and warranty coverage, signaling a broader collaboration between Quantum Computing and the financial institution as quantum-secure infrastructure gains traction in enterprise markets.

QUBT Price Action: Quantum Computer shares are trading lower by 6.23% to $17.76 at publication on Tuesday.
