Studying Tech Diplomacy—Introduction to the Special Issue on Tech Diplomacy
Global Policy, EarlyView.ABSTRACT This article serves as an introduction to the special issue on tech diplomacy, exploring its emergence and evolution as a distinct approach to global affairs in the era of the Fourth Industrial Revolution. Originating with Denmark's 2017 “TechPlomacy” initiative, tech diplomacy has gained global momentum, with over two dozen countries adopting

Verification of quantum discord
, 2012 We introduce a measurement-based method for verifying quantum discord of any bipartite quantum system. We show that by performing an informationally complete POVM (IC-POVM) on one subsystem and checking the commutativity of the conditional states of the other subsystem, quantum discord from the second subsystem to the first can be verified.

Fiscal Equalisation in Australian Federalism: Share and Share Alike?
Australian Journal of Politics &History, EarlyView.The sharing of revenue between the states to achieve fiscal equality has long been an important and internationally notable feature of Australian federalism. While horizontal fiscal equalisation is always prone to dispute, unprecedented conflict erupted in the Australian system in the second decade of this century and resulted in changes that brought ...

Quantum correlations between each two-level system in a pair of atoms and general coherent fields
Results in Physics, 2016 The quantitative description of the quantum correlations between each two-level system in a two-atom system and the coherent fields initially defined in a coherent state in the framework of power-law potentials (PLPCSs) is considered.

Levantine Hacksilber and the flow of silver in early Mediterranean commerce
Archaeometry, EarlyView.Abstract This study presents a comprehensive approach to provenancing ancient silver artefacts, introducing a novel algorithm to correct for mass‐dependent isotope fractionation. Applied to a Pb isotope database of 281 Hacksilber samples from southern Levantine hoards (1700–600 BCE) and compared with approximately 7000 galena ores from Spain to Iran ...

Dynamics of quantum correlations in four-qubit XXZ Heisenberg model with external magnetic field
Results in PhysicsIn this paper we argue about the quantum correlation (quantum entanglement and geometric quantum discord) in four-qubit XXZ Heisenberg Model. Here, the influence of uniform magnetic field on the dynamics of quantum correlation in cases of the ...
