Protecting quantum entanglement from amplitude damping

Quantum entanglement is a critical resource for quantum information and quantum computation. However, entanglement of a quantum system is subjected to change due to the interaction with the environment. One typical result of the interaction is the amplitude damping that usually results in the reduction of the entanglement. Here we propose a protocol to protect quantum entanglement from the amplitude damping by applying Hadamard and CNOT gates. As opposed to some recently studied methods, the scheme presented here does not require weak measurement in the reversal process, leading to a faster recovery of entanglement. We propose a possible experimental implementation based on linear optical system

Pemikiran Mohammad Ilyas Tentang Penyatuan Kalender Islam Internasional

The object of this study is Mohammad Ilyas\u27s concept of the unification of InternationalIslamic calendar. The Method of analysis is descriptif-analysis. The results of this researchshow that Mohammad Ilyas\u27s concept of the unification of International Islamic Calendarbased on the hisab of the crescent visibility and the International Lunar Date Line (ILDL).The Ilyas\u27s criteria of the crescent visibility use two parameter, i.e. geocentric relative altitudeand relatif azimut. The application of Mohammad Ilyas\u27s concept of the crescent visibility asthe unification of International Islamic calendar can\u27t accepted by Indonesia Moslem. Thisproblem is caused by the difference criteria between Indonesia Moslem (Indonesia ReligiousAffair) of the crescent visibility and Ilyas. Ilyas\u27s concept of International Lunar Date Line isalways change every month. This condition is cause the difference in the beginning of the dayon the first month in the region of the country

Studi Komparasi Karakteristik Asap Cair Hasil Pirolisis dari Kulit Durian, Pelepah dan Tandan Kosong Sawit dengan Pemurnian secara Distilasi

Liquid smoke is one of the modern methods of food preservation. It made from biomass containing cellulose, hemicellulose and lignin. The purpose of this research was to generate and compare the characteristics of liquid smoke results from pyrolysis feedstock durian shell, EFB and palm midrib and distillation refining. The method is carried out every feedstock in the pyrolysis temperature range of 300-350 °C and distilled temperature at of 175 °C. Then, performed analysis of the characteristics of liquid smoke compounds using GC/MS and test pH using a pH meter. The yield of liquid smoke pyrolysis results of each feedstock is durian shell 42.474%; 49.647% EFB and palm midrib 44.66%. From the analysis of GC/MS, acetic acid has the highest percent area among 16 dominant compounds in liquid smoke of pyrolysis results and among 14 dominant compounds after distillation. Percent acetic acid in the area of liquid smoke each feedstock pyrolysis results changed after the distillation of durian shell 54.17% to 62.8%; EFB 48.83% to 74.39% and palm midrib 52.19% to 41.14%. The percent area of phenolic compounds that act as antioxidants skin durian is 1.38% to 2.72%; EFB 5.28% to 6.56% ; palm midrib 9.12 % to 5.84 %. Liquid smoke pH values obtained after distillation is the durian shell 3.8; EFB 3.5 and 3.4 of palm midrib

Kompetensi Penyuluh Pertanian di Tujuh Kecamatan di Kabupaten Bekasi, Jawa Barat

Agricultural Extension agents must acquire certain competencies so as to perform well in doing their jobs. Competencies were the combination of knowledge, skills and abilities. Competencies both had intellectual as well as practical dimensions that were served as the bases of the agents\u27 professional expertise, especially in promoting their clientele well being. As knowledge, technology and work environment changed, the Agricultural agents should also adjust their competencies. In this conjunction, the Agricultural agents\u27 working environment in the seven sub-districts in the district of Bekasi had tremendously changed in the last thirty years. A vast area of well-irrigated rice fields had been converted into industrial as well as urban estates. This in turn created a lot of small and land less farmers who no longer practice rice cultivation as before. Consequently, the agents\u27 client profiles were subsequently changed as well. The research question then, “What were the Agricultural Agents\u27 needed competencies so as to serve these people well?” To address this question, a descriptive study was implemented in those sub-districts. Twenty-six Agricultural Agents were interviewed. The obtained results pointed out that the agents perceived that: (1) Extension Program Development, (2) Promotion of Farmers\u27 Participation, (3) Conducting Education for Farmers, (4) Organizing Farmers, (5) Agricultural Information, (6) Socio-economic aspects of Agriculture, (7) Agricultural Subject Matter, and (8) Communication, as the competencies that they needed
