SBQuantum

SBQuantum is a Canadian quantum technology company based in Sherbrooke, Quebec, a city that has become a recognized hub for quantum research and commercialization. The company develops quantum diamond magnetic sensing technology, using nitrogen-vacancy (NV) centers in diamond to detect and measure magnetic fields with high precision and richer data than conventional magnetometry. Its stated mission is to "reveal the invisible" by turning quantum magnetic sensing into practical, field-proven hardware and software for positioning, navigation, and other demanding applications. SBQuantum's core offering is a diamond-based quantum magnetic sensor paired with a magnetic mapping solution. The company describes itself as an end-to-end partner to clients: its integrated product first detects magnetic fields, then interprets changes in magnetic resonance lines, and finally visualizes the output in a customizable platform that produces outputs such as total magnetic field maps and tilt angle data. This combination of sensing hardware and data visualization is aimed at users who need to operate where satellite navigation is unreliable or unavailable. The company targets several markets. In defense and homeland security, quantum magnetometry can support navigation and detection in GPS-denied environments. In public safety, the technology can assist with locating and mapping magnetic signatures. In commercial navigation and space applications, SBQuantum positions its sensors as a complement or alternative to conventional positioning systems. The company has also sponsored educational webinar series to explain quantum diamond magnetometry and its potential impact. SBQuantum was founded by a team of four: David Roy-Guay (Founder, CTO), Eric Giroux (Co-Founder, CEO), Vincent Halde (Co-Founder, Technical Director), and Olivier Bernard (Co-Founder, Lead Designer). The leadership team combines technical and commercial roles, reflecting the company's focus on translating quantum research into deployable products. As a privately held company, SBQuantum does not disclose public financial statements, and its exact founding year is not stated in the available evidence. SBQuantum operates in the emerging quantum sensing sector, where it competes with other magnetometry and quantum sensing developers. Its differentiation rests on diamond NV magnetometry, which offers advantages in sensitivity, size, weight, and power compared with some traditional magnetic sensors. By focusing on field-proven, integrated solutions rather than laboratory demonstrations, SBQuantum aims to serve government, defense, and commercial customers that require robust magnetic sensing in real-world conditions.

SBQuantum was founded in Sherbrooke, Quebec, Canada, a city that has developed into a quantum technology hub. The company was established by four co-founders: David Roy-Guay, Eric Giroux, Vincent Halde, and Olivier Bernard. Their goal was to commercialize quantum diamond magnetometry, a sensing approach that uses nitrogen-vacancy (NV) centers in diamond to measure magnetic fields with high sensitivity and rich data content. From its base in Sherbrooke, SBQuantum focused on turning laboratory quantum sensing techniques into field-proven products. The company developed a diamond-based quantum magnetic sensor and an accompanying magnetic mapping solution. This integrated system detects magnetic fields, analyzes changes in magnetic resonance lines, and visualizes the results in a customizable platform that can produce total magnetic field maps and tilt angle data. SBQuantum has positioned its technology for applications where precise magnetic sensing is critical, including defense, homeland security, public safety, and commercial navigation. The company has also engaged in educational outreach, sponsoring a webinar series to explain quantum diamond magnetometry and its potential to change fields such as navigation and national security. As a privately held company, SBQuantum has not disclosed a precise founding year in the available evidence, nor does it publish public financial statements. Its leadership team remains composed of the original co-founders, with Eric Giroux as CEO, David Roy-Guay as CTO, Vincent Halde as Technical Director, and Olivier Bernard as Lead Designer. The company continues to operate from Sherbrooke and serves clients internationally in the quantum sensing market.
