Certifying position-momentum entanglement at telecommunication wavelengths

The successful employment of high-dimensional quantum correlations and its integration in telecommunication infrastructures is vital in cutting-edge quantum technologies for increasing robustness and key generation rate. Position-momentum Einstein-Podolsky-Rosen (EPR) entanglement of photon pairs are a promising resource of such high-dimensional quantum correlations. Here, we experimentally certify EPR correlations of photon pairs generated by spontaneous parametric down-conversion (SPDC) in a nonlinear crystal with type-0 phase-matching at telecommunication wavelength for the first time. To experimentally observe EPR entanglement, we perform scanning measurements in the near- and far-field planes of the signal and idler modes. We certify EPR correlations with high statistical significance of up to 45 standard deviations. Furthermore, we determine the entanglement of formation of our source to be greater than one, indicating a dimensionality of greater than 2. Operating at telecommunication wavelengths around 1550 nm, our source is compatible with today’s deployed telecommunication infrastructure, thus paving the way for integrating sources of high-dimensional entanglement into quantum-communication infrastructures.

Telecommunication Infrastructure Development and FDI into Asian Developing Nations

This study strives to evaluate the effects of infrastructure availability and development on foreign direct investment (FDI) in host developing nations.Employing fixed effects panel estimation technique, panel data for 23 Asian developing countries, from 1990-2009 is used with heteroscedasticity corrected standard errors. The results reveal a strong favourable impact of telecom infrastructure (measured by mobile subscriptions) in drawing inward FDI. Therefore, it is concluded that a country with improved infrastructure in general and telecom infrastructure in particular is likely to pull in more FDI. Other variables such as market size, economic development, and currency valuation (measured by exchange rate) appear important in captivating multinational investors, as they exhibit significant coefficients. On the contrary, high-inflation significantly deters inward FDI.

THE ROLE OF OVER THE TOP (OTT) SERVICE ON UTILIZATION OF TELECOMMUNICATION INFRASTRUCTURE BASED ON INDONESIAN TAX AND NON-TAX POLICY

The rapid development of Over the Top (OTT) services has enabled consumers to enjoy high service quality from technology even more. Nevertheless, OTT also brings other effects for telecommunications companies in Indonesia; namely, there are legal problems and obstacles faced regarding regulation and practice of tax and non-tax for OTT business providers because these services do not have a form of cooperation with telecommunications operators. In addition, the model of policies and regulations is still uncertain regarding how the tax and non-tax imposition should be in Indonesia. This study uses a normative juridical research method emphasizing secondary data (library research) with three legal materials, namely primary, secondary and tertiary legal materials. The research includes data searching and inventory and laws and regulations related to tax and non-tax imposition for OTT services on the utilization of telecommunication infrastructure and other relevant sources. Results of the study determine the extent to which regulations on the tax and non-tax imposition govern OTT media in Indonesia to understand and find the policy and regulatory issues related to tax and non-tax imposition practices faced by OTT business actors. In addition, it also aims to find obstacles in policy formulation and stipulation of tax and non-tax regulations for OTT business actors in Indonesia. Further, it seeks to find a tax and non-tax policies and regulations model for OTT business actors in Indonesia through a service collaboration, comparative, and normative approaches. Hence, this will also open up opportunities to increase state revenue from the imposition of tax and non-tax from all OTT service providers, both national and international.

The Heterogeneous Influence of Infrastructure Construction on China’s Urban Green and Smart Development—The Threshold Effect of Urban Scale

The construction of green and smart cities is an important approach to enhancing the level of high-quality development and modern governance, in which infrastructure construction is the antecedent condition. From the perspective of green total factor productivity (GTFP), this paper adopts the SBM–GML (Slack-Based Model and Global Malmquist–Luenberger) index to measure the urban green and smart development level (GSDL) considering smart input–output factors. Based on the panel data of China’s 223 prefecture-level cities from 2005 to 2018, the dynamic impacts, temporal, and spatial differences of energy, transportation, and telecommunication infrastructure construction on the urban GSDL are discussed, and the threshold effects of urban scale are tested. The following conclusions are drawn: (1) On the whole, energy infrastructure inhibits the urban GSDL, while transportation and telecommunication infrastructures significantly promote it. There are distinct spatial and temporal characteristics among the impacts of these three infrastructures on the urban GSDL, in which the facilitating role of transportation and telecommunication infrastructures are further enhanced during the period of 2013–2018. Furthermore, the impacts of these three infrastructures on the urban GSDL all show “U” shape in terms of non-linearity. (2) Economic development level and industrial structure have significant positive effects on the urban GSDL, whereas human capital only has positive effect in the northeast and southwest regions, and government scale shows no positive impact yet. (3) There is a single threshold for the impact of urban scale on these three infrastructures, among which the impacts of energy and transportation infrastructures on the urban GSDL remain consistent before and after the threshold, while the impact of telecommunication infrastructure on the urban GSDL varies from having no significance to being positive when crossing the threshold. Thus, capital investment for infrastructure construction should be further allocated reasonably, the positive potential of human capital should be fully released, and the urban scale should be appropriately controlled in the future.

E-Government, Governance and Corruption in Asian countries

In developing countries, the implementation of e-government is at greater risk of failure when the corruption is still high. This paper examines the effect of e-government on the level of corruption in 47 developing countries in Asia using E-Government Development Index which is divided into components of online service, human capital, telecommunication infrastructure and e-participation. This paper also places the role of governance in government to moderate the relationship between e-government and perceptions of corruption. The result shows that implementation of e-government and governance has increased the perception of corruption with telecommunications infrastructure has the most significant effect.

Assessment Of The Effect Of Socio-Economic Infrasturcture On Rural Economy In Kaduna State, Nigeria

The paper examines the effect of socio-economic infrastructure of the rural areas on the rural economy in Kaduna State. The study adopts a correlation analysis, a Multicollinearity and Cronbach Alpha Reliability tests as well as regression analysis on primary data. Findings from the study reveal that there is a positive relationship between socioeconomic infrastructure and rural economy, while the multicollinearity test shows absence of high correlation among the independent variables and the Cronbach Alpha confirms internal consistency of the variables. Furthermore, the regression analysis indicates that socio-economic infrastructure, particularly road, electricity supply, market and telecommunication infrastructure all have positive and statistically significant effects on the rural economy. The paper therefore, recommends that governments should increase efforts towards developing the infrastructure in the rural areas in order to facilitate the growth of the economy in the rural sectors.

E-government in Jordan and Studying the Extent of the E-government Development Index According to the United Nations Report

This research paper presented the experiences of a group of countries as pioneering models in the field of e-government and compared them to Jordan with the aim of evaluating their status at the global and continental levels. Methods for measuring and evaluating the development of E-government suggested using a method called multi-practice are a practice of multi methodology, which combines methods and techniques, and proposes to evaluate the tangible and intangible benefits of e-government, which shows that the multiplicity of aspects of measurement may lead to a kind of reliability in e-government also Methods for measuring and evaluating e-government performance proposed by international organizations. By United Nations E-Government Survey The comparison and evaluation were done using the e-government maturity index issued by the United Nations EGDI, which includes the Telecommunication Infrastructure Index (TII) and The human capital Index (HCI), and the Online Service Index (OSI) e-government service sub-indicator, in the period between 2008 and 2020, and this comparison comes in order to benefit from these experiences, redress weaknesses, and exploit the opportunities available to Jordan to develop its e-government, keep pace with the global movement and raise its efficiency in a way that serves the goals of sustainable development The results were that Jordan, according to by United Nations E-Government Survey Jordanian e-government is still in the first generation It has many improvements performance on the e-government index the change in the EGDI. Some comparisons of Jordan with Arab countries have been presented in the EGDI in 2020 for the United Nations report
