China’s Quantum Sensing Ecosystem: From Deep-Sea Diamonds to Drone-Mounted Submarine Hunters
In April 2025, a team from the University of Science and Technology of China published what might be the most consequential quantum sensing result of the decade — and almost nobody in the Western security community noticed. They had taken a nitrogen-vacancy center diamond magnetometer, packaged it into a ruggedized…

Rydberg Atom Sensors: The Quantum Technology That Could Rewrite the Rules of Electronic Warfare
In April 2024, a startup nobody outside Beijing's quantum corridor had heard of quietly incorporated in Zhongguancun. Kewei Quantum (spun out of the Beijing Academy of Quantum Information Sciences) completed its first funding round within months of founding and began marketing two product lines: atomic clocks and Rydberg atom electromagnetic…

AI and Quantum Sensing: A Perfect Synergy
AI and quantum sensing complement each other perfectly. Quantum sensors provide the rich, nuanced data about physical reality at its smallest scales; AI provides the means to interpret and act on that data in real time. This synergy is already evident in cutting-edge projects – from AI algorithms cleaning up…

Quantum Sensing – Key Use Cases
At its core, quantum sensing goes beyond classical measurement limits. Traditional sensors – from thermometers to microphones – are ultimately constrained by thermal noise, electronic noise, and even the fundamental “shot noise” of particles. Quantum sensors break past these limits by exploiting the quirky properties of quantum mechanics, like superposition…

Quantum Sensing and Navigation as Sovereignty
Quantum sensing leverages quantum phenomena (entanglement, superposition, etc.) to achieve measurement precision beyond classical limits. Importantly, many quantum sensors are nearing deployable maturity, unlike quantum computers that remain experimental. Atomic clocks, quantum optical gyroscopes, gravity sensors and the like are transitioning from labs to real-world pilots. This means a nation…

Quantum LiDAR vs. Quantum Radar
Quantum radar and quantum LiDAR are no longer science fiction – they are emerging reality, albeit in early stages. They differ in technology and likely timelines: expect to hear more about quantum LiDAR in commercial products soon, while quantum radar will continue to be a strategic project for defense and…

Quantum Sensing – Introduction and Taxonomy
Quantum sensing is poised to augment and in some cases revolutionize how we measure the world. Its unique ability to leverage fundamental quantum phenomena – superposition, entanglement, and more – means it can achieve what was once thought impossible: detecting the seemingly undetectable. This field stands at a nexus between…
