Quantum inertial navigation is the use of quantum sensors (quantum accelerometers and quantum gyroscopes) to determine position, velocity, and orientation without relying on external signals like GPS.
Why it matters. GPS-denied navigation is critical for submarines, underground vehicles, autonomous systems in contested environments, and space applications. Conventional inertial navigation systems accumulate drift errors over time, requiring periodic GPS corrections. Quantum inertial navigation systems, based on atom interferometry, offer dramatically lower drift rates, potentially enabling autonomous navigation over much longer periods without external correction. This is considered one of the highest-impact near-term applications of quantum technology, with active development programs in defense and aerospace.
How it connects. Quantum inertial navigation sensors require the same precision timing, pulse control, and synchronization capabilities that the Qblox Cluster provides for quantum computing experiments. The Cluster's deterministic operation and low-latency feedback architecture are directly applicable to the control requirements of field-deployed quantum sensors. Learn more about the Qblox Cluster.
