Aggregate combat modeling using high-resolution simulation: "the "meeting engagement"scenario as a case study

This paper illustrates a methodology for developing aggregated combat models using high-resolution simulation and the Markovian Lanchester process. The details of the mathematical models involved in a high-resolution simulation process of a Meeting Engagement tactical scenario are presented, along with a theoretical discussion on the Markovian Lanchester model. The output from the discrete event simulation model is used to estimate the attrition rates for an aggregated Lanchester model. A comparative study of various statistical estimation methods suitable for such estimation is also presented.

Violation of Bell's inequality with quantum-dot single-photon sources

We investigate the possibility of realizing a loophole-free violation of Bell's inequality using deterministic single-photon sources. We provide a detailed analysis of a scheme to achieve such violations over long distances with immediate extensions to device-independent quantum key distribution. We investigate the effect of key experimental imperfections that are unavoidable in real-world single-photon sources including the finite degree of photon indistinguishability, single-photon purity, and the overall source efficiency. We benchmark the performance requirements to state-of-the-art deterministic single-photon sources based on quantum dots in photonic nanostructures and find that experimental realizations appear to be within reach. We also evaluate the requirements for a post-selected version of the protocol, which relaxes the demanding requirements with respect to the source efficiency.
