Heritage
From Atomic Clocks to Quantum Systems
Many of the technologies that define modern timing systems are fundamentally quantum in nature.
FEI has extensive experience developing and manufacturing atomic clocks and frequency standards that use the predictable behavior of atoms to generate highly accurate and stable frequency references. These systems form the foundation of critical applications across space, defense, communications, navigation, and scientific research.
Building on this heritage, FEI continues to advance new quantum-enabled technologies designed to improve timing, sensing, and system performance.
