The faithful distribution of entanglement over noisy channels is a vital prerequisite for many quantum technological applications. Quantum information can be encoded in different degrees freedom (DOF) photons, where each encoding comes with its own advantages and disadvantages respect to noise resilience practicality manipulation. In this work, we experimentally implement deterministic purifica...

We present a delay-line polarization Sagnac (1) interferometer that utilizes the increased laser power which will likely be available to future advanced detectors (2) to greatly simplify many laser and interferometer control requirement. We describe how the signal sidebands and the local oscillator are made common path by using a polarizing beamsplitter and controlling the circulating light's p...

We were interested in comparing the characteristics of polarization sensitivity in Atlantic salmon to those in Pacific salmon. Here we show that the common ancestor to the clade containing Salmo salar, Oncorhynchus mykiss, O. nerka, O. clarkii and Salvelinus fontinalis has the trait of ultraviolet polarization sensitivity. We examined spectral and polarization sensitivity of juvenile Atlantic s...

We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.

The polarization of light carries much useful information about the environment. Biological studies have shown that some animal species use polarization information for navigation and other purposes. It has been previously shown that a bioinspired polarization-difference imaging (PDI) technique can facilitate detection and feature extraction of targets in scattering media. It has also been esta...

We made regionally specific measurement of the hyperfine polarization kS ·Il of Rb atoms in the vicinity s,10−5 cmd of coated and uncoated Pyrex glass surfaces in optical pumping cells. This is in contrast to the previous hyperfine polarization studies, where the quantity measured is the bulk hyperfine polarization, which depends on surface interactions averaged over the entire cell surfaces. W...

We present integrated polarization properties of nearby spiral galaxies at 4.8 GHz, and models for the integrated polarization of spiral galaxy disks as a function of inclination. Spiral galaxies in our sample have observed integrated fractional polarization in the range . 1% to 17.6%. At inclinations less than 50 degrees, the fractional polarization depends mostly on the ratio of random to reg...
