Quantum and AI Navigation Earns Recognition from Time: A Deep Dive Q&A

When GPS falters, most of us experience a minor inconvenience—perhaps a brief moment of frustration while waiting for the signal to return. However, for military and civilian aircraft, the stakes are much higher. These vessels face increasing threats from GPS jamming and spoofing by both nation-states and other entities.

One promising solution lies in geomagnetic navigation systems, which leverage quantum sensors to navigate using the Earth’s magnetic field. SandboxAQ, a company innovating at the intersection of AI and quantum technology, has developed the AQNav system, a groundbreaking navigation solution that is unspoofable, even in the most challenging environments. After extensive trials with the U.S. Air Force (USAF), Boeing, and Airbus, AQNav was successfully demonstrated aboard a USAF C-17 Globemaster III in July 2024. Recently, this technology earned a spot on Time Magazine’s list of best innovations for 2024.

In this Q&A, Luca Ferrara, SandboxAQ’s General Manager of Navigation, discusses the development of AQNav, the challenges posed by operating quantum systems in noisy military environments, and how AI and quantum technologies are merging to create a new era of navigation.

What Sparked the Creation of AQNav?

The concept of magnetic navigation is far from new—compasses have been used for centuries. However, Ferrara explains that the idea of using more advanced magnetic field data to aid navigation had its origins in academic research. When SandboxAQ was still housed within Google’s innovation lab, X, in 2020, the team began focusing on applications of quantum sensing technology. Ferrara quickly realized that their expertise in magnetometry could be applied to the critical problem of GPS navigation.

By combining the latest advancements in quantum sensing with modern software capabilities, SandboxAQ was able to develop AQNav in a relatively short period. From conceptualization in 2020 to a real-time demonstration on a C-17 aircraft, the journey of AQNav highlights the rapid pace of innovation when quantum technologies are paired with AI.

How Does AQNav Work?

AQNav operates through a modular architecture that treats sensors in a network as data creation units. These sensors provide enough information to allow AI to extract a signal from Earth’s magnetic field, all while compensating for any distortions caused by the aircraft itself. Essentially, the system allows aircraft to navigate as though they are invisible to their own interference.

The software then cleans the data streams and uses existing magnetic field maps to create navigation solutions. This process relies on innovations in state estimation theory, with the help of geophysicists who design algorithms that can accurately interpret the Earth’s magnetic field for precise positioning.

Overcoming Environmental Noise in Military Aircraft

A key challenge for AQNav was dealing with environmental noise aboard military aircraft, which are filled with electronic systems that interfere with sensitive quantum sensors. Ferrara explains that while this is a significant obstacle, the team was able to leverage existing calibration techniques, such as those used in attitude and heading reference systems (AHRS), to mitigate the impact of noise.

By carefully calibrating the magnetometers and positioning the sensors away from noise sources, AQNav is able to maintain the accuracy required for reliable navigation. The success of this approach was demonstrated during real-world tests with the USAF.

The Future of Quantum Navigation

While AQNav may not yet surpass the accuracy of GPS in every situation, Ferrara and his team are confident that magnetic navigation will continue to improve over time. The technology is particularly useful in aerospace applications, where GPS signals are often unreliable or compromised. As the technology matures, AQNav could become a critical tool for ensuring the safety and reliability of military and civilian aircraft alike.

Given the importance of data in making these systems work, AI is playing a crucial role in optimizing navigation, much like how it’s being used in a variety of other fields.

A Passion Project for Ferrara

For Ferrara, AQNav is more than just a technological achievement—it’s a passion project. When COVID-19 hit, Ferrara found himself looking for something new to immerse himself in. After joining the SandboxAQ team, what started as a side project soon became his full-time focus. Within three years, Ferrara and a small team of experts took AQNav from concept to reality, all while pushing the boundaries of what’s possible with quantum and AI technologies.

This passion is fueled by the potential real-world impact of AQNav. As Ferrara notes, “A lot of cool technology never makes it to market, but I never had to question whether this product would benefit society.” By pushing the limits of innovation, AQNav has the potential to revolutionize navigation for years to come.

As AI continues to merge with quantum technologies, it’s clear that we’re only scratching the surface of what’s possible. AQNav is just one example of how these powerful tools can come together to solve real-world problems, and it’s a testament to the bright future of AI-powered navigation.
