Bounds on universal quantum computation with perturbed 2d cluster states

Motivated by the possibility of universal quantum computation under noise perturbations, we compute the phase diagram of the 2d cluster state Hamiltonian in the presence of Ising terms and magnetic fields. Unlike in previous analysis of perturbed 2d cluster states, we find strong evidence of a very well defined cluster phase, separated from a polarized phase by a line of 1st and 2nd order transitions compatible with the 3d Ising universality class and a tricritical end point. The phase boundary sets an upper bound for the amount of perturbation in the system so that its ground state is still useful for measurement-based quantum computation purposes. Moreover, we also compute the local fidelity with the unperturbed 2d cluster state. Besides a classical approximation, we determine the phase diagram by combining series expansions and variational infinite Projected entangled-Pair States (iPEPS) methods. Our work constitutes the first analysis of the non-trivial effect of few-body perturbations in the 2d cluster state, which is of relevance for experimental proposals.Comment: 7 pages, 4 figures, revised version, to appear in PR

The Effect of Competency to Work Effectiveness: Case Study on Women’s Principal

Gender equality is the natural equation or equality between women and men. If we look from the physical point of view, a woman and man are absolutely very different. When it comes to one’s job profession, woman tends to use 90% of their feelings and 10% logic, which is very inversely proportionate to a man, who uses 90% logic and 10% feeling. This research aims to determine the Professional Competence, Social Competence and Personality Competence to the Effectiveness of Work. The research method used is explanatory research and associative research by taking 83 female Principals, starting from Kindergarten level to Senior High School with sampling technique being purposive sampling. Based on the result of research that simultaneously affects the effectiveness of work program of female principals. The partial dominance of program effectiveness is the competence of personality, social competence and professional competence. The dominance of 44.1% (R2 ) can be explained by the model, while the rest of which is 55.9%, influenced by other factors outside the research model. It is recommended that, for future purposes, the female principals should be trained to become principals by the Department of Education and Culture along with Human Resources and Human Resource Development Agency.     Keywords: professional, personal, social, competency, effectivenes

Strategi Pengembangan UMKM Berbasis Kearifan Lokal Dalam Mendukung Perekonomian Daerah Pasca Pandemi Covid-19

Research and development of small and medium enterprises based on local wisdom in supporting the regional economy after the COVID-19 pandemic (a case study of the Sambas district) aims to determine the appropriate strategy to be implemented to empower local SMEs in the Sambas area, which is divided into three fields, namely weaving, rattan, and pandanus. The number of samples for each field is 27 for weaving, 32 for rattan, and 4 for pandanus. Meanwhile, the analysis used in this research is through the analysis of Force Field Analysis (FFA) and Strength, Weakness, Opportunity, and Threat (SWOT). Based on the FFA analysis, it was found that the main driving factors were the selling price of the product, the price of raw materials, and advances in information technology, while the critical inhibiting factors were online marketing, total turnover, and business management. Based on the SWOT analysis through the EFAS and IFAS matrices, there are similarities in strategy taking: product innovation and differentiation, product sales via online or e-commerce, product quality and product quality improvement, and social campaigns to promote traditional values to encourage sales.   Keywords: SMEs Based on Local Wisdom, Weaving, Pandan, Rattan, Development   Abstrak Pengembangan UMKM berbasis kearifan lokal dalam mendukung perekonomian daerah pasca pandemi covid-19 (studi kasus kabupaten sambas) bertujuan untuk mengetahui strategi yang sesuai untuk diimplementasikan demi memberdayakan UKM lokal daerah sambas yang dibagi menjadi tiga bidang yaitu tenun, rotan, dan pandan.

Is Neolithic land use correlated with demography? An evaluation of pollen-derived land cover and radiocarbon-inferred demographic change from Central Europe

The transformation of natural landscapes in Middle Europe began in the Neolithic as a result of the introduction of food-producing economies. This paper examines the relation between land-cover and demographic change in a regionally restricted case study. The study area is the Western Lake Constance area which has very detailed palynological as well as archaeological records. We compare land-cover change derived from nine pollen records using a pseudo-biomisation approach with 14C date probability density functions from archaeological sites which serve as a demographic proxy. We chose the Lake Constance area as a regional example where the pollen signal integrates a larger spatial pattern. The land-cover reconstructions for this region show first notable impacts at the Middle to Young Neolithic transition. The beginning of the Bronze Age is characterised by increases of arable land and pasture/meadow, whereas the deciduous woodland decreases dramatically. Changes in the land-cover classes show a correlation with the 14C density curve: the correlation is best with secondary woodland in the Young Neolithic which reflects the lake shore settlement dynamics. In the Early Bronze Age, the radiocarbon density correlates with open land-cover classes, such as pasture, meadow and arable land, reflecting a change in the land-use strategy. The close overall correspondence between the two archives implies that population dynamics and land-cover change were intrinsically linked. We therefore see human impact as a key driver for vegetation change in the Neolithic. Climate might have an influence on vegetation development, but the changes caused by human land use are clearly detectable from Neolithic times, at least in these densely settled, mid-altitude landscapes

Probing non-linear MHD stability of the EDA H-mode in ASDEX Upgrade

Regimes of operation in tokamaks that are devoid of large ELMs have to be better understood to extrapolate their applicability to reactor-relevant devices. This paper describes non-linear extended MHD simulations that use an experimental equilibrium from an EDA H-mode in ASDEX Upgrade. Linear ideal MHD analysis indicates that the operational point lies slightly inside of the stable region. The non-linear simulations with the visco-resistive extended MHD code, JOREK, sustain non-axisymmetric perturbations that are linearly most unstable with toroidal mode numbers of n = \{6 \dots 9\}, but non-linearly higher and lower n become driven and the low-n become dominant. The poloidal mode velocity during the linear phase is found to correspond to the expected velocity for resistive ballooning modes. The perturbations that exist in the simulations have somewhat smaller poloidal wavenumbers (k_{\theta} \sim 0.1 to 0.5 cm^{-1} ) than the experimental expectations for the quasi-coherent mode in EDA, and cause non-negligible transport in both the heat and particle channels. In the transition from linear to non-linear phase, the mode frequency chirps down from approximately 35 kHz to 13 kHz, which corresponds approximately to the lower end of frequencies that are typically observed in EDA H-modes in ASDEX Upgrade
