Coherence effects on estimating general sub-Rayleigh object distribution moments
نویسندگان
چکیده
Quantum Fisher information and signal-to-noise ratio bounds are derived for the estimation of moments general partially coherent objects. Under an asymptotic analysis in sub-Rayleigh regime, these shown to be less restrictive than those incoherent case. This leaves open possibility more accurately estimating object distribution when is coherent.

Coherence effects on pion spectrum distribution
The effects of two kinds of coherent lengths, the wave packet length of the emitter and the radius of the coherent source, on pion spectrum distribution are studied. It is shown that both coherent lengths can cause abundant pions at low momentum, but the DCC size effects on pion spectrum distribution is more important. So observing abundant pions at low momentum may be taken as a signal of DCC ...
متن کاملOn Estimating Frequency Moments of Data Streams
Space-economical estimation of the pth frequency moments, defined asFp = Pn i=1|fi| , for p > 0, are of interest in estimating all-pairs distances in a large data matrix [14], machine learning, and in data stream computation. Random sketches formed by the inner product of the frequency vector f1, . . . , fn with a suitably chosen random vector were pioneered by Alon, Matias and Szegedy [1], and...
متن کاملOn Moving Object Reconstruction By Moments
Recent research using statistical moments to describe moving shapes through an image sequence has led to an interest in reconstructing moving shapes from their moment description. This paper discusses how the moment description through a series of frames might be used to predict missing or intermediate frames within a sequence. Additionally, this highlights generic aspects of moment reconstruct...
متن کاملEstimating Average Causal Effects Under General Interference
This paper presents randomization-based methods for estimating average causal effects under arbitrary interference of known form. Conservative estimators of the randomization variance of the average treatment effects estimators are presented, as is justification for confidence intervals based on a normal approximation. Examples relevant to research in environmental protection, networks experime...
متن کاملEstimating Frequency Moments of Streams
We will develop algorithms that can approximate Fk by making one pass of the stream and using a small amount of memory o(n+m). Frequency moments have a number of applications. F0 represents the number of distinct elements in the streams (which the FM-sketch from last class estimates using O(log n) space. F1 is the number of elements in the stream m. F2 is used in database optimization engines t...
