SBQuantum, a Sherbrooke, Quebec-based developer of compact quantum diamond magnetometers using NV centers, has raised $4M in an oversubscribed seed round led by Quantonation. The sensors enable vector magnetometry for detecting and classifying metallic objects in GPS-denied environments via 'Magnetic Intelligence' software. The capital will fund U.S. expansion through Zero Drift Technologies and product scaling.
Quantum Sensing Seed Frenzy Heats
The round closed amid surging investor interest in quantum magnetometers for defense navigation. Australian peer Deteqt raised A$5M seed (~$3.3M USD) just days earlier for chip-scale sensors targeting GPS-free positioning. Quantacet and Investissement Québec also joined SBQuantum's syndicate, signaling Quebec's quantum ecosystem momentum. This twin seed wave underscores capital flowing to resilient PNT tech amid GPS jamming threats.
GPS Jamming Spurs Sensor Demand
Geopolitical conflicts like those in Ukraine expose GPS vulnerabilities, driving demand for alternatives in drones, submarines, and urban ops. Traditional magnetometers suffer drift and low sensitivity in denied environments. Quantum NV-diamond sensors offer order-of-magnitude improvements in compactness and precision without cryogenic cooling. SBQuantum's platform targets defense ISR, public safety screening, and space mapping.
Vector Magnetometry Without Bias Coils
SBQuantum integrates NV-center diamond sensors with proprietary algorithms for 3D magnetic modeling and object classification. Unlike lab-focused rivals like Qnami's scanning microscopes, SBQuantum delivers portable, field-deployable systems for drones and AUVs. Recent tests in -60°C Arctic conditions and STRATOS balloons at 40km validate ruggedness.
As founder David Roy-Guay stated:
“The timing of this investment reflects the growing urgency around resilient navigation and threat detection capabilities in both the defense and commercial sectors.”
Elite Quantum VCs Validate Tech
Quantonation, the first dedicated quantum VC with €220M Fund II, led alongside Quebec specialists Quantacet and government-backed Investissement Québec. Their portfolios feature sensing peers like Qnami and Phantom Photonics, indicating conviction in SBQuantum's space-proven magnetometers. This mix blends deep physics expertise with regional scaling support post-$15M+ in R&D contracts from DoD, ESA, and CSA.
Quantum Sensors Market Scales Rapidly
The quantum sensors market stood at $786.6M in 2022, projected to reach $1.42B by 2030 at 7.8% CAGR per Grand View Research. Government pushes like ESA FutureEO and Canada's National Quantum Strategy fuel adoption in PNT and GEOINT. SBQuantum, a spinout from Université de Sherbrooke's Institut Quantique, leads with orbital deployments via MagQuest on SpaceX.
Institut Quantique Spinout Hits Stride
Founder David Roy-Guay invented the core NV-diamond tech during his PhD and postdoc at Institut Quantique, commercializing it as SBQuantum's first space-qualified sensor. New CEO Eric Giroux brings defense commercialization experience from RaySecur. Fractional CFO Mitch Salis adds serial exits like Lendful's acquisition. This blend accelerates from prototypes to defense pilots.
U.S. Expansion Targets Defense
Funds enable Zero Drift Technologies launch in Cambridge, MA, for U.S. defense access while retaining IP in Canada. Ongoing hires include electrical designers and senior software engineers for algorithm productionization. ESA/CSA contracts for space testing and Spire Global satellite partnership position demos with builders like 55+ agencies.
