Quantum game theory has emerged as a promising candidate to further the understanding of quantum correlations. Motivated by this, it is demonstrated that pure strategy Nash equilibria can be utilized mechanism witness and determine correlation. By combining with Bayesian theory, constant-sum designed in which players are competing against each other crucially gain at player’s expense. Subsequently, found mixed only necessary when considering correlation for game. This reveals game-theoretic...

Based on 1H NMR studies, subtle electronic factors rather than pre-organisation dictate the binding stoichiometry of new, norbornene based, anion hosts 1 and 2 with acetate, however, dihydrogenphosphate appears to be based solely steric constraints.

We have measured the thermopower of an untwinned crystal ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}}}$ in both a and b directions. In direction is about +0.7 \ensuremath{\mu}V/K just above ${\mathit{T}}_{\mathit{c}}$, while opposite sign -6 \ensuremath{\mu}V/K. The sharp peak observed at ${\mathit{T}}_{\mathit{c}}$ twinned crystals only clearly present a-axis measurement. At temperatures close to room temperature becomes...

Abstract Six new, charge‐neutral norbornene‐based receptors 1a , 1b – 3a 3b were prepared, and their ability to interact with simple anions in DMSO was investigated using 1 H NMR UV/Vis spectroscopy. Binding of dihydrogenphosphate by the six appeared be based solely on steric constraints. In contrast, binding stoichiometry acetate controlled subtle electronic factors.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

Abstract Quantum discord has been utilised in order to find quantum advantage an extension of the Clauser, Horne, Shimony, and Holt game. By writing game explicitly as a Bayesian game, resulting is modified such payoff’s are different. Crucially, restrictions imposed on measurements that Alice Bob can perform. imposing these restrictions, it found there exists beyond entanglement for given state. This shown by decomposing expected payoff into classical term. optimising over payoff, limit...

Witnessing quantum correlation in real, practical experimental setups is a key focus for the development of near-future technologies. While there are several protocols witnessing entanglement, detecting discord remains far more elusive. A recently proposed witness offers an experimentally accessible setup which allows to be witnessed through nonlinear combination functions. Interestingly, can mapped Bayesian game theory allowing extended generalization witness. Subsequently, it shown that...

The complex amplitude of oscillations probability density function upper bounded by subsequently results in being discord. This gives experimental observable can be used quantify witness interferometry experiment, and provide another avenue technologies continue develop.

These asymmetries are revealed in the expected payoff for version of Prisoner's dilemma, demonstrating certain advantages can be found given subsystems depending on performed network. this setup allows measurement-induced control one respective parties.

We present the evolution of quantum correlation in energy teleportation (QET) protocol using discord, instead traditionally used entanglement entropy. In QET protocol, where local observations and conditional operations are repeated, correlations become nontrivial because statistical creation mixed states. this paper, we use discord as a measure states investigate its relationship to teleported phase transitions. During process Alice Bob performing QET, one would expect that between is...

In this article, we explore a feedback-control protocol in different quantum field theories (QFTs) to study the correlation nonunitary evolution of systems. Traditional studies on QFTs focus entanglement pure states under unitary evolution, however, examine mixed using energy teleportation (QET), which is an transfer by utilizing ground state entanglement, and introduce discord as measure. QET involves midcircuit measurement, disrupts entanglement. Despite this, our analysis demonstrates...
