Navigation by detecting anomalies in Earth's magnetic field

Click For Summary
SUMMARY

The discussion centers on "Quantum Navigation," a method for navigation that detects anomalies in Earth's magnetic field. It highlights the use of NV-centres for creating sensitive compasses and emphasizes the potential of quantum interference of cold atoms for high-precision inertial navigation and gravity sensing. These technologies have been in laboratory use for years and are currently being commercialized by various companies and universities worldwide.

Today I came across an article (not from a authoritative journal) about "Quantum Navigation".
It is about a method to do navigation by detecting anomalies in Earth's magnetic field. I tried (and failed) to find a reference which described what this technology has to do with QM. Does anyone know about such a relationship, or is "quantum" just used to name this technology for hyping purposes?
 
Physics news on Phys.org
There are a bunch of quantum technologies that could potentially be used for navigation.
This can be a simple as using e.g. NV-centres to make an extremely sensitive compass.

However, the most interesting technologies for applications are using quantum interference of cold atoms (meaning it is really "quantum").
These can be used for inertial navigation (with a much, much higher precision than say a laser gyro) as well as for gravity sensors.

These technologies have been used in the lab for a number of years; a number of companies and universities around the world are now in the process of commercializing them.
