An Operational Framework for Nonclassicality in Quantum Communication Networks [PDF]
arXivQuantum resources such as entanglement and quantum communication offer significant advantages in distributed information processing. We develop an operational framework for realizing these enhancements in resource-constrained quantum networks. We first compute linear constraints on the input/output probabilities that arise in classical networks with ...

Expertise localization discovered through correlation of key term distribution and community detection in co-author networks [PDF]
arXiv, 2014 We present an efficient and effective automatic method for determining the research focus of scientific communities found in co-authorship networks. It utilizes bibliographic data from a database to form the network, followed by fastgreedy community detection to identify communities within large connected components of the network.

Advanced Optical Materials, EarlyView.Sequential indolo‐fusion π‐extension as a rational design strategy to further narrow the emission bandwidth of multi‐resonance thermally activated delayed fluorescence is introduced. By fusing one or two additional indole moieties to the periphery of Cz‐B, gradual spectra narrowing and accelerated triplet–singlet exciton spin conversion are ...

Advanced Photonics Research, EarlyView.Telecom‐band quantum light sources have significant practical applications in this domain. This study reports the high‐performance telecom‐wavelength biphoton generation from a hot vapor cell of 87Rb. For the first time, the beat phenomenon in the autocorrelation function of the signal photon with telecom wavelength due to the velocity‐selective ...

Advanced Photonics Research, EarlyView.This work introduces a low‐loss diffractive neural network, fabricated using an imprinting technique with parowax material, for recognizing and manipulating the topological charge of orbital angular momentum (OAM) waves. It is also demonstrated that the low‐loss diffractive network can perform mathematical operations based on the topological charges of
