QMX Insights · May 2026 A passenger jet crosses the Baltic at thirty-five thousand feet. Nothing looks wrong from a window seat. But in the cockpit, the satellite navigation has just gone blank — or worse, started reporting a position that is confidently, dangerously false. The crew switches to backup procedures, and the flight lands safely. Then it happens to the next aircraft, and the next. This is no longer a rare event. Reporting over the past two years has documented ten

A magnetometer measures magnetic fields. Conventional magnetometers — the kind used in smartphones and some industrial sensors — are useful, but they have limits. They struggle with noise, require calibration, and miss the faint signals that carry the most valuable information. Most people have never heard of a quantum magnetometer. That's about to change. A quantum magnetometer operates on an entirely different principle. By exploiting the behaviour of atoms at the quantum l

GPS is remarkable — but it has a vulnerability. It depends on satellite signals that can be jammed, spoofed, or simply unavailable underground, underwater, or in contested environments. For autonomous vehicles, defence platforms, and critical infrastructure operators, GPS denial is not a hypothetical risk. It is a planning assumption. The question is: what replaces it? One answer lies in Earth's own magnetic field. Every location on the planet has a unique magnetic signature

Every bridge, pipeline, and power cable is telling a story. Most of the time, no one is listening. Metal structures under stress generate subtle changes in their magnetic signature. Corrosion, fatigue, and developing faults all leave detectable traces — long before they become visible, audible, or catastrophic. The challenge is not that the signals don't exist. The challenge is that conventional sensors aren't sensitive enough to read them. Quantum magnetic sensing changes th

The minerals that power the clean energy transition — lithium, cobalt, nickel, copper — are not running out. But the easy deposits are gone. The next generation of resources lies deeper, in more complex geology, in regions where conventional exploration methods reach their limits. Airborne magnetic surveys have long been a standard tool in geophysical exploration. Magnetometers carried by aircraft can map subsurface structures across large areas quickly and cost-effectively.

The human body generates magnetic fields. The heart, the brain, and the peripheral nervous system all produce electrical activity — and every electrical current generates a corresponding magnetic field. These biomagnetic signals carry clinical information of extraordinary richness. The magnetic field of the heart encodes cardiac function in a way that complements and in some respects surpasses the electrocardiogram. The magnetic field of the brain, mapped in detail, reveals n
