Quantum X Labs Demonstrates Fractional Frequency Stability in Ramsey-CPT Atomic Clock Platform - Quantum Computing Report

Quantum hardware developer Quantum X Labs Inc. Ltd. (Nasdaq: QXL) has announced the successful laboratory demonstration of a high-sensitivity atomic clock through its wholly-owned subsidiary, Quantum X Labs Ltd. Built upon the company’s Ramsey Coherent Population Trapping (Ramsey-CPT) interrogation platform, the system achieved a short-term fractional frequency stability metric of 1×10−13 at an interval of one second. The development track aims to establish a scalable physical architecture for compact, chip-scale atomic clocks (CSACs) targeted at infrastructure operating independently of external timing signals. The refinement of chip-scale atomic timing addresses an engineering vulnerability in positioning, navigation, and timing (PNT) frameworks: the reliance [...]
