Highly symmetric POVMs and their informational power
We discuss the dependence of the Shannon entropy of rank-1 normalized finite POVMs on the choice of the input state, looking for the states that minimize this quantity. To distinguish the class of measurements where the problem can be solved analytically, we introduce the notion of highly symmetric POVMs and classify them in dimension two (for qubits). In this case we prove that the entropy is ...
متن کاملHighly Symmetric Expanders
Expander graphs are relevant to theoretical computer science in addition to the construction of high-performance switching networks. In communication network applications, a high degree of symmetry in the underlying topology is often advantageous, as it may reduce the complexity of designing and analyzing switching and routing algorithms. We give explicit constructions of expander graphs that a...
متن کاملAn informational rationale for committee gatekeeping power
This essay investigates the relationship between congressional committees, information, and gatekeeping power. It shows that the power to obstruct legislation increases the amount of information transmitted by committees in equilibrium. As a consequence, rational floor actors will make it somewhat difficult, but not impossible, to discharge committees. Some committees will have effective gateke...
متن کاملHighly Symmetric Subgraphs of Hypercubes
Two questions are considered, namely (i) How many colors are needed for a coloring of the n-cube without monochromatic quadrangles or hexagons? We show that four colors suffice and thereby settle a problem of Erdos. (ii) Which vertex-transitive induced subgraphs does a hypercube have? An interesting graph has come up in this context: If we delete a Hamming code from the 7-cube, the resulting gr...
