Canada Is Building a Quantum GPS. The Military Is Paying for It.
Canada is buying prototype quantum magnetometers the same way the United States bought GPS in the 1970s: before anyone could prove a civilian business case, before the technology was mature, and before the public understood why they would ever need it.
SBQuantum, a Quebec-based quantum sensing startup, announced two defence contracts with the Canadian Department of National Defence worth a combined $3 million CAD ($2.2 million USD) — $1.05 million through DND's IDEaS Test Drive program for portable multi-sensor field arrays and $1.95 million through Innovation, Science and Economic Development Canada's Innovative Solutions Canada program for UAV-mounted quantum sensor integration. Eric Giroux, SBQuantum's CEO, described the parallel in the company's announcement: magnetic navigation solutions provide accurate and reliable positioning information that cannot be blocked or distorted — a sentence that could have been written in 1978 about NAVSTAR.
GPS took two decades to reach full operational capacity and cost billions. The original system was built almost entirely for nuclear weapons delivery and naval navigation. Nobody in the 1970s sat down and decided to invent the market for turn-by-turn directions, location sharing, or food delivery tracking. The infrastructure came first; the applications followed.
SBQuantum's approach uses nitrogen-vacancy (NV) diamond quantum sensors — a type of magnetometer that detects extremely faint magnetic fields by measuring how the spin states of nitrogen vacancy defects in diamond respond to external magnetic fields. Unlike GPS, which relies on satellites that can be jammed, spoofed, or knocked out with anti-satellite weapons, a magnetic field is a physical property of the Earth itself. It cannot be blocked the way a satellite signal can. For militaries operating in contested or GPS-denied environments — dense urban terrain, underground facilities, jamming-heavy theaters — that difference is the entire point.
The technology has a history of overclaiming. GPS-independent navigation has been the next big thing in quantum sensing for roughly twenty years. Commercial adoption has been slow, partly because quantum magnetometers have struggled with thermal stability, size, and power consumption in field conditions. The sensor previously launched into low-Earth orbit as part of the U.S. National Geospatial-Intelligence Agency's MagQuest challenge — space-qualified, but orbit is a controlled environment, not a Ukrainian winter.
These contracts are not production orders. They are validation instruments. The IDEaS Test Drive program explicitly funds operational testing: success means the hardware works in the field, not that it has been adopted. A $1 million contract from a NATO defense budget is real money for a startup, but it is a fraction of what a single production contract with a major NATO prime would cost — typically ten to fifty times larger. SBQuantum raised a $4 million CAD seed round in April 2026 and appointed Giroux CEO. The company has funding, a technical team, and now, officially, government validation of its approach.
What the contracts actually test is whether NV diamond magnetometers can maintain sensitivity and thermal stability in the conditions where navies, armies, and air forces operate. If they can — if the field testing produces clean enough data — the training data and manufacturing scale that follows starts to close the gap between "military validation" and "commercial product." That is how GPS became ubiquitous: not through a grand civilian adoption plan, but through twenty years of military procurement generating the components, manufacturing processes, and trained workforce that eventually made civilian applications affordable.
Whether quantum magnetometers follow that same arc, or end up as a specialized military tool that never crosses over, is what these contracts are designed to answer.
