Superadditivity of distillable entanglement From Quantum Teleportation
Somshubhro Bandyopadhyay, Vwani Roychowdhury
We show that the phenomenon of superadditivity of distillable entanglement observed in multipartite quantum systems results from the consideration of states created during the exec…
Theory of aces: high score by skill or luck?
M. V. Simkin, V. P. Roychowdhury
We studied the distribution of World War I fighter pilots by the number of victories they were credited with, along with casualty reports. Using the maximum entropy method we obtai…
Boundary effects to the entanglement entropy and two-site entanglement of the spin-1 valence-bond solid
Heng Fan, Vladimir Korepin, Vwani Roychowdhury +2
We investigate the von Neumann entropy of a block of subsystem for the valence-bond solid (VBS) state with general open boundary conditions. We show that the effect of the boundary…
Low Latency Wireless Ad-Hoc Networking: Power and Bandwidth Challenges and a Hierarchical Solution
Nima Sarshar, Behnam A. Rezaei, Vwani P. Roychowdhury
This paper is concerned with the scaling of the number of hops in a large scale wireless ad-hoc network (WANET), a quantity we call network latency. A large network latency affects…
A General Framework for Scalability and Performance Analysis of DHT Routing Systems
Joseph S. Kong, Jesse S. A. Bridgewater, Vwani P. Roychowdhury
In recent years, many DHT-based P2P systems have been proposed, analyzed, and certain deployments have reached a global scale with nearly one million nodes. One is thus faced with…
Finite Percolation at a Multiple of the Threshold
Nima Sarshar, Patrick Oscar Boykin, Vwani P. Roychowdhury
Bond percolation on infinite heavy-tailed power-law random networks lacks a proper phase transition; or one may say, there is a phase transition at {\em zero percolation probabilit…
Re-inventing Willis
M. V. Simkin, V. P. Roychowdhury
Scientists often re-invent things that were long known. Here we review these activities as related to the mechanism of producing power law distributions, originally proposed in 192…
