We investigate a two-qubit system to understand the relationship between concurrence and mutual information, where former determines amount of quantum entanglement, whereas latter is its classical residue after performing local projective measurement. For given ensemble random pure states, in which values are uniformly distributed, we calculate joint probability information. Although zero infor...

A bstract We derive the property of strong superadditivity mutual information arising from Markov vacuum state in a conformal field theory and subadditivity entanglement entropy. show this inequality encodes unitarity bounds for different types fields. These are precisely ones that saturate free This has natural explanation terms possibility localizing algebras on null surfaces. particular cont...

We show that the free-riding problem in short-lived teams is not as severe as previously thought. Two critical conditions are: team members can observe each other’s effort periodically, which makes mutual monitoring possible; technology is convex (increasing marginal returns) or has a “completion benefit.” In principal-agent settings, mutual monitoring reduces the necessary wage payment to indu...

from the perspective of the states that their foreign policy is based on geo-economy, the economy is the most important mechanism of influence in target areas. therefore, with the strengthening of trade relations would be in an appropriate level to increase the mutual relations.  after the independence of central eurasian states, geographical - political events of central eurasia led to the cre...
