0. Introduction and summary. The analysis of data from the gravitational-wave detectors that are currently under construction in several countries will be a challenging problem. The reason is that gravitational-vawe signals are expected to be extremely weak and often very rare. Therefore it will be of great importance to implement optimal statistical methods to extract all possible information ...

The quantum Fisher information (QFI), as a function of states, measures the amount that state carries about an unknown parameter. (entanglement-assisted) QFI channel is defined to be maximum output assuming entangled input over single probe and ancilla. In metrology, people are interested in calculating N identical copies when N??, which called asymptotic QFI. Over years, researchers found vari...

A method is introduced to track the object’s motion and estimate its pose from multiple cameras. We focus on direct estimation of the 3D pose from 2D image sequences. We derive a distributed solution that is equivalent to the centralized pose estimation from multiple cameras. Moreover, we show that, by using a proper rotation between each camera and a fixed camera view, we can rely on independe...
