The two Josephson junction flux qubit with large tunneling amplitude

In this paper we discuss solid-state nanoelectronic realizations of Josephson flux qubits with large tunneling amplitude between the two macroscopic states. The latter can be controlled via the height and wells form of the potential barrier, which is determined by quantum-state engineering of the flux qubit circuit. The simplest circuit of the flux qubit is a superconducting loop interrupted by a Josephson nanoscale tunnel junction. The tunneling amplitude between two macroscopically different states can be essentially increased, by engineering of the qubit circuit, if tunnel junction is replaced by a ScS contact. However, only Josephson tunnel junctions are particularly suitable for large-scale integration circuits and quantum detectors with preset-day technology. To overcome this difficulty we consider here the flux qubit with high-level energy separation between "ground" and "excited" states, which consists of a superconducting loop with two low-capacitance Josephson tunnel junctions in series. We demonstrate that for real parameters of resonant superposition between the two macroscopic states the tunneling amplitude can reach values greater than 1K. Analytical results for the tunneling amplitude obtained within semiclassical approximation by instanton technique show good correlation with a numerical solution.Comment: 8 pages, 4 figure

Fundamental Measurements in Economics and in the Theory of Consciousness

A new constructivist approach to modeling in economics and theory of consciousness is proposed. The state of elementary object is defined as a set of its measurable consumer properties. A proprietor's refusal or consent for the offered transaction is considered as a result of elementary economic measurement. Elementary (indivisible) technology, in which the object's consumer values are variable, in this case can be formalized as a generalized economic measurement. The algebra of such measurements has been constructed. It has been shown that in the general case the quantummechanical formalism of the theory of selective measurements is required for description of such conditions. The economic analogs of the elementary slit experiments in physics have been created. The proposed approach can be also used for consciousness modeling

Fundamental Measurements in Economics and in the Theory of Consciousness (Manifestation of quantum-mechanical properties of economic objects in slit measurements)

A new constructivist approach to modeling in economics and theory of consciousness is proposed. The state of elementary object is defined as a set of its measurable consumer properties. A proprietor's refusal or consent for the offered transaction is considered as a result of elementary economic measurement. We were also able to obtain the classical interpretation of the quantum-mechanical law of addition of probabilities by introducing a number of new notions. The principle of “local equity” assumes the transaction completed (regardless of the result) of the states of transaction partners are not changed in connection with the reception of new information on proposed offers or adopted decisions (consent or refusal of the transaction). However it has no relation to the paradoxes of quantum theory connected with non-local interaction of entangled states. In the economic systems the mechanism of entangling has a classical interpretation, while the quantum-mechanical formalism of the description of states appears as a result of idealization of the selection mechanism in the proprietor's consciousness

Were Ukrainian regions too different to start interregional confrontation: economic, social and ecological convergence aspects?

This article deals with analysis of economic, social and ecological disparities of Ukrainian regions. Regional economic disparities are measured through the convergence concept and the article employs panel data analysis with fixed and random effects estimations. Our empirical results show the presence of economic convergence in Ukrainian regions. Initially it was found that poor regions do grow relatively faster than the rich. Moreover, the difference between poor and rich regions has been decreased 1.8 times during 1999 and 2010. In addition, it was found that the presence of ecological convergence in the Ukraine and initially ‘clean’ regions do increase pollution faster than initially ‘dirty’ regions. That is, Ukrainian regions were onverging to some environmental steady state through the process of increasing pollution. Ukrainian regions were also experiencing health onvergence with negative policy implications, since all regions do converge to some health levels through an increase in morbidity. The economic growth of Ukrainian regions was achieved through sacrificing environmental situations and increased morbidity. Therefore, there were no clear economic reasons to start interregional confrontation that has taken place in the Ukraine, since all regions were on the same track of development
