The shipment signals expanding global interest in advanced quantum hardware designed for the evolving landscape of cybersecurity and communication networks.

The company’s newly deployed product is a self-contained entangled photon generator, built using Spontaneous Parametric Down-Conversion and structured around a bulk-format periodically-poled lithium niobate crystal.

Operating within the C-band, a range compatible with mainstream fiber-optic systems, the device is engineered for seamless integration into existing telecom infrastructure and experimental setups exploring quantum communication protocols.

Yong Meng Sua, Chief Technology Officer at Quantum Computing ( QUBT ), said the product forms an integral component of the company’s quantum cybersecurity ecosystem, a platform recognized with a 2024 Edison Award. “We are thrilled to see this capability deployed in the field to empower next-generation quantum communication,” Sua said.

This photon source is rooted in patented designs co-authored by Yuping Huang, Interim CEO, and Lac Nguyen, which offer a scalable framework for quantum key distribution.

Quantum Computing ( QUBT ) plans to evolve the product further by integrating thin-film lithium niobate (TFLN) to enhance miniaturization and performance at its U.S. foundry.

Pouya Dianat, Quantum Computing’s Chief Revenue Officer, highlighted this shipment as a validation of the company’s global commercial roadmap.

This development supports Quantum Computing’s broader effort to position itself as a key supplier of high-performance tools for quantum communications and cybersecurity applications worldwide.

According to Benzinga Pro, QUBT stock has gained over 3000% in the past year. Investors can gain exposure to the stock via SPDR S&P Software & Services ETF ( XSW ) .

Price Action: QUBT shares are trading lower by 1.52% to $20.90 at last check Tuesday.
