SBQuantum, a Canadian company, has received 3 million CAD (2.2 million USD) in defense contracts to bring their quantum magnetometer speed into critical situations, signaling a fundamental shift in military positioning and surveillance. These Canadian government-funded strategic prizes aim to bring superior diamond-based sensing technology into active war regions. The new Canadian Defense Industrial Strategy lists quantum sensing as a “Key Sovereign Capability” for national security.
The Navigating in Contested Environments
Modern military operations depend on GPS and other GNSS. These systems’ structural faults are exploited by modern warfare. GPS signals are weak when they reach Earth, making them easy to spoof, jam, or degrade. Electronic warfare fighting zones can blind autonomous drones and endanger ground vehicles if GPS is denied.
Inertial Navigation Systems (INS) have been used as backups by militaries, although they “drift,” becoming less accurate with time. SBQuantum‘s Magnetic Navigation (MagNav) uses Earth instead of the sky for an entirely independent alternative. Geomagnetic fields vary locally in every square meter of the planet. By mapping these abnormalities with precise sensors, a vehicle may position itself with pinpoint accuracy without satellite manipulation.

Innovative Use of Nitrogen-Vacancy Diamonds
This technical advance is powered by the Diamond Quantum Magnetometer. SBQuantum’s magnetometer uses atomic-scale quantum characteristics to avoid thermal drift and bulkiness. The device is comprised of synthetic diamond crystal with billions of NV centers. These faults occur when a nitrogen atom replaces a carbon atom in the diamond lattice, causing a vacancy that releases two electrons.
Electrons with quantum spin motion like ultra-sensitive, atomic-scale compass needles. Data is extracted by lively a green laser on the diamond and exposing it to resonant microwaves. The Optically Detected Magnetic Resonance, electron spins generate red light at different intensities when they interact with external magnetic fields. SBQuantum can read the local magnetic field with amazing accuracy by monitoring this light.
Vectorial Sensing Tactical Advantage
SBQuantum’s hardware’s “vectorial” capacity is a major benefit. Traditional scalar sensors simply measure magnetic field intensity, leaving large blind regions. SBQuantum’s diamond crystal has four sensing axes in a compact region, allowing it to measure the field’s amplitude and three-dimensional direction.
The company successfully integrated lasers, optics, and CPUs into a 483-gram, 6-watt machine the size of a carton of milk. Integration into military platforms from hand-held equipment to autonomous aircraft requires portability.
An Analysis of the $3 Million CAD Investment
The Canadian Armed Forces will receive infrastructure-free, jam-resistant positioning, navigation, and timing (PNT) options through two main operational channels with the new funding:
- Field-Deployable Arrays ($1.05 Million CAD): This DND IDEaS contract covers multi-sensor magnetometer systems. Field operators will collect real-world performance data and train the system’s algorithms with these portable units.
- UAV Hardware Integration ($1.95 Million CAD): An Innovative Solutions Canada (ISC) project, this project mounts tiny sensor suites on UAVs. This configuration will automatically locate buried structures and landmarks in tough or limited locations.

Magnetic Intelligence and Noise Cancellation
Magnetic navigation often faces “noise”. Military armored vehicles and rifles can cause magnetic interference that conceals Earth’s natural signal. SBQuantum created “Magnetic Intelligence” software using unique machine-learning techniques to tackle this.
These algorithms can dynamically identify localized background noise from the underlying geomagnetic field because the sensor gathers vector data. The software simplifies this complex data into location information and object classification without requiring operators to examine raw wave readouts.
Space Validation to Global Strategy
After space achievements, military deployment follows. SBQuantum was a top finalist in the U.S. Government’s MagQuest Challenge to create the World Magnetic Model 2030. The business successfully launched its sensor into orbit in March 2026 to test it amid high radiation and temperature.
These sensors improve the ISR capabilities beyond navigation the operators can track subsurface infrastructure and detect submerged or hidden metallic dangers that standard sensors cannot.

The Future of the Quantum Defence Ecosystem
SBQuantum’s rise indicates geopolitical shift toward tech-centric warfare. The 2017 University de Sherbrooke Institute Quantique spinoff closed a $4 million CAD seed financing to drive commercial growth. Zero Drift Technologies, a Cambridge, Massachusetts sibling company, serves foreign customers while protecting Canadian IP.
By adding these sensors to its arsenal, Canada is leading the quantum-enabled defense era. As global conflicts increasingly use electronic warfare, absolute navigation sovereignty independent of satellite infrastructure is a strategic concern. SBQuantum will display these active testing configurations at CANSEC 2026 and the DND IDEaS Marketplace in Ottawa.
