World-First Submarine Test Proves Quantum Clocks Can Keep Perfect Time Under Extreme Ocean Pressure In a groundbreaking maritime and defense technology milestone, researchers have successfully demonstrated that a quantum clock can operate accurately aboard a submarine, even under intense underwater pressure and harsh environmental conditions. This marks the first-ever real-world submarine test of quantum timekeeping technology. Accurate timekeeping is critical for navigation, communication, and

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time with incredible precision. #quantumphysics #atomicclock #time #atoms #electrons #quantum | NOVA l PBS
