In this paper we present a necessary and sufficient condition of distinguishability of bipartite quantum states. It is shown that the operators to reliably distinguish states need only rounds of projective measurements and classical comunication. We also present a necessary condition of distinguishability of bipartite quantum states which is simple and general. With this condition one can get m...

Parsimony is very important in system modeling as it is closely related to model interpretability. In this paper, a scheme for constructing accurate and parsimonious fuzzy models by generating distinguishable fuzzy sets is proposed, in which the distinguishability of input space partitioning is measured by a so-called “local” entropy. By maximizing this entropy measure the optimal number of mer...

The dissipative dynamics of the spin chain coupled to non-Markovian magnonic reservoir was studied. chirality is formed due magnetoelectric coupling. We explored sign trace distance derivative and found alternating positive/negative periods in system's time evolution. negative associated with flow information from system bath decrease states distinguishability, while positive related opposite d...

We will examine the problem of distinguishing between database instances and values in models which incorporate object-identities and recursive data-structures. We will show that the notion of observational distinguishability is intricately linked to the languages available for querying a database. In particular we will show that, given a simple query language incorporating a test for equality ...

Any two-qubit state can be represented, geometrically, as an ellipsoid with a certain size and center located within the Bloch sphere of one of the qubits. Points of this ellipsoid represent the postmeasurement states when the other qubit is measured. Based on the most demolition concept in the definition of quantum discord, we study the amount of demolition when the two post-measurement states...

The problem of the distinguishability of the Bell states is considered. In the entangled Bell states the individual particles are a mixture. The implication of this for " local interpretation " of the dense coding and teleportation protocols is examined.
