Abstract
We show how quantum entanglement and squeezing can be employed in measuring a position in space, gaining an accuracy increase over classical localization procedures. We develop a positioning protocol based on frequency-entanglement of number-squeezed pulses, which may be used also for synchronizing the clocks of distant parties, and show how the accuracy increase scales with the system resources and how it compares with analogous, but classical, protocols.
