Quantum X Labs Enhances Its Quantum Platform for Defense and Aerospace with Unique Combination of Atomic Clock and Rydberg RF Sensing Technologies

The Company is developing an integration of its patent-pending quantum atomic clock technology with Rydberg atom-based RF sensing technology

TEL AVIV, Israel, Sept. 28, 2026 (GLOBE NEWSWIRE) -- Quantum X Labs Inc. Ltd. (Nasdaq: QXL) (“Quantum X” or the “Company”) today announced that its wholly-owned subsidiary, Quantum X Labs Ltd. (“Quantum X Labs” or “QXL”), is working on the development of Rydberg atom-based radio-frequency (“RF”) sensing technology and its integration with the Company’s patent-pending quantum atomic clock technology, expanding QXL’s work in atom-based quantum sensing.

The development program is currently underway in QXL’s laboratories and is intended to combine two complementary atom-based capabilities: high-precision atomic timing and quantum-enabled RF sensing. The integration work builds on QXL’s quantum atomic clock platform, for which the Company has a pending patent application. QXL previously announced the successful demonstration of its high-sensitivity atomic clock based on its Ramsey Coherent Population Trapping (“Ramsey-CPT”) platform.

QXL is now working to expand its atom-based sensing capabilities by developing Rydberg atom RF sensing technology and working toward its integration with the Company’s atomic clock platform. The Rydberg RF sensing technology and the proposed integration are separate development activities and are not covered by the Company’s pending atomic clock patent application.

Rydberg RF sensing uses atoms excited into highly energetic states known as Rydberg states. In these states, atoms become highly sensitive to electromagnetic fields, creating the potential to use the atoms themselves as RF sensing elements. Changes in atomic states caused by incoming RF signals can be optically interrogated, providing a different approach to detecting and characterizing electromagnetic signals compared with conventional electronic RF sensing. QXL’s development program is focused on bringing this capability together with its existing atomic timing technology.

By integrating these capabilities through the development program, QXL is working toward an atom-based sensing architecture that combines precision timing, frequency reference and RF sensing within a unified technological platform.

The development is aligned with a broader defense and aerospace industry shift toward atom-based quantum sensing and precision timing technologies for operations in increasingly complex and contested electromagnetic environments. The Defense Advanced Research Projects Agency (DARPA) has advanced both Rydberg atom-based RF receivers for potential applications, including electromagnetic spectrum operations, radar and communications, as well as precision atomic-clock technologies intended to maintain critical timing capabilities in environments where access to GPS may be degraded or unavailable.

The aerospace sector is also evaluating Rydberg sensing for space applications. A 2026 study conducted in collaboration between Airbus Defence and Space, Quantum Valley Ideas Laboratories and the German Aerospace Center (DLR) examined the feasibility of using Rydberg atom-based sensors in spaceborne radar systems, reflecting growing interest in transitioning atom-based quantum sensing from laboratory research toward potential aerospace and defense applications.

QXL believes that this evolution strengthens the potential relevance of combining precision atomic timing with atom-based RF sensing within a common technology architecture for future aerospace and defense systems.

“We see significant technological value in bringing different atom-based sensing capabilities together rather than developing each technology entirely in isolation,” said Prof. Nir Sharon, Chief Quantum Scientist of Quantum X Labs. “Our atomic clock provides a precision timing and frequency foundation. We are now developing Rydberg atom RF sensing technology in our laboratories and working toward integrating these capabilities. Our objective is to create an architecture in which atomic technology can provide both precise timing and information about the surrounding RF environment.”

QXL intends to continue laboratory development, testing and integration work toward demonstrating the combined architecture.

The Rydberg RF sensing technology and its integration with QXL’s atomic clock remain under development. The Company has not yet demonstrated a fully integrated atomic clock and Rydberg RF sensing system, and there can be no assurance that the development program will achieve its intended technical performance or result in a commercially viable product.
