Thermodynamic model of social influence on two-dimensional square lattice: Case for two features
Jozef Genzor, Vladimir Buzek, Andrej Gendiar
We propose a thermodynamic multi-state spin model in order to describe equilibrial behavior of a society. Our model is inspired by the Axelrod model used in social network studies.…
Quantum walks as a probe of structural anomalies in graphs
Mark Hillery, Hongjun Zheng, Edgar Feldman +2
We study how quantum walks can be used to find structural anomalies in graphs via several examples. Two of our examples are based on star graphs, graphs with a single central verte…
Simulation of indivisible qubit channels in collision models
Tomas Rybar, Sergey N. Filippov, Mario Ziman +1
A sequence of controlled collisions between a quantum system and its environment (composed of a set of quantum objects) naturally simulates (with arbitrary precision) any Markovian…
Toward protocols for quantum-ensured privacy and secure voting
Marianna Bonanome, Vladimir Buzek, Mark Hillery +1
We present a number of schemes that use quantum mechanics to preserve privacy, in particular, we show that entangled quantum states can be useful in maintaining privacy. We further…
Scavenging quantum information: Multiple observations of quantum systems
Peter Rapcan, John Calsamiglia, Ramon Munoz-Tapia +2
Given an unknown state of a qudit that has already been measured optimally, can one still extract any information about the original unknown state? Clearly, after a maximally infor…
Optimal unambiguous comparison of two unknown squeezed vacua
Stefano Olivares, Michal Sedlak, Peter Rapcan +2
We propose a scheme for unambiguous state comparison (USC) of two unknown squeezed vacuum states of an electromagnetic field. Our setup is based on linear optical elements and phot…
