Quantum sensors exploit superposition, entanglement, and quantum interference to measure physical quantities with precision beyond the classical limit. For defence, this means detecting submarines by their magnetic signature, navigating without GPS using quantum inertial sensors, mapping underground structures through gravity gradients, and timing operations with atomic clock stability. This session provides a technically grounded assessment of each sensing modality, its current readiness level, and realistic deployment timelines.
Quantum sensing encompasses several distinct technologies at different maturity levels. Atomic clocks based on optical lattice transitions (strontium, ytterbium) achieve fractional frequency stability below 10^-18, already deployed in national timing infrastructure. Quantum magnetometers using nitrogen-vacancy centres in diamond or optically pumped alkali vapours detect fields at the femtotesla level, enabling anomaly detection at distances relevant to anti-submarine warfare. Quantum gravimeters based on cold atom interferometry measure local gravity with micro-Gal precision, applicable to underground facility detection and geological survey.
For defence organisations, the challenge is separating technologies that are field-deployable today from those that remain laboratory demonstrations. This session examines each modality through published performance data, identifies the engineering gaps between laboratory and operational environments (vibration, temperature, size, weight, and power constraints), and provides a realistic technology readiness assessment. Participants leave with a framework for evaluating vendor claims and prioritising investment in quantum sensing capabilities most relevant to their operational requirements.
