Transportable Quantum Accelerator Could Replace GPS’s Dependence on Satellite Signals
(ZDNet) Scientists from Imperial College London and UK laser instrument maker M Squared have demonstrated a way to measure how super-cooled atoms respond when inside an accelerating vehicle. The demonstrates that a transportable quantum accelerator could address GPS’s dependence on satellite signals, which can be jammed or spoofed by an attacker, rendering the system useless for navigational information.
Accelerometers are used for navigation, but as the researchers explain, they quickly lose accuracy over time unless aided by satellite signals. The satellite-free navigational device they created relies on M Squared’s laser, which cools atoms in a chamber to the point where they behave in a quantum way, as both matter and waves.
