  This study presents a quantum strategy for simultaneous estimation of two
physical quantities using different entanglement resources. We explore the
utilization of positively or negatively timecorrelated photons. The proposed
method enables the detection of central position and relative velocity of
multibody systems, as well as precise measurement of size and velocity of
moving objects. Comparative analysis with other strategies reveals the superior
quantum advantage of our approach, particularly when appropriate entanglement
sources with high entanglement degree are employed. These findings contribute
to advancing our understanding of quantum strategies for accurate measurements.
