A quantum positioning system uses quantum sensors (quantum accelerometers, gyroscopes, and clocks) to determine geographic position and time without relying on satellite signals like GPS.
Why it matters. GPS is vulnerable to jamming, spoofing, and signal denial in enclosed environments (underwater, underground, indoors). A quantum positioning system based on high-precision inertial sensors could provide autonomous, unjammable navigation for defense, transportation, and critical infrastructure. While fully integrated quantum positioning systems are still in development, the individual quantum sensor components (atomic clocks, quantum accelerometers, quantum gyroscopes) are maturing rapidly.
How it connects. The precision timing, pulse sequencing, and synchronization capabilities of the Qblox Cluster are directly relevant to the control requirements of the quantum sensors that make up a positioning system. Learn more about the Qblox Cluster.
