Nonlocal dissipative tunneling for high-fidelity quantum-state transfer between distant parties

In this work, we propose the nonlocal tunneling mechanism for high-fidelity state transfer between distant parties. The nonlocal tunneling follows from the overlap between the distant sending and receiving wave functions, which is indirectlymediated by the off-resonant normal modes of a quantum channel. This channel is made up of a network of dissipative quantum systems exhibiting the same bosonic or fermionic statistical nature as the sender and receiver. We demonstrate that the incoherence arising from quantum channel nonidealities is almost completely circumvented by the tunneling mechanism, which thus affords a high-fidelity transfer process.

Civil Society and Political Parties in the Period of Transition

The major aim of Mr. Marada's project was to investigate the role of political parties on the one hand, and various institutional forms of civil society on the other, in the process of establishing mechanisms of political decision-making and policy-formation in Czechoslovakia and the Czech Republic, after November 1989. Mr. Marada wanted to examine what consequences the interplay and tensions between political parties and institutions of civil society had on the status and practical understanding of citizenship and civil society. At the beginning of his research Mr. Marada found that, while the sphere of the political was relatively clearly defined, the phenomenon of civil society required a conceptual clarification. He devoted a great deal of time to analysing the emergence, development, and disintegration of Civic Forum as the major agent of the regime change and subsequent political reforms. Alongside this analysis is a commentary on Czech society in general, drawing on established research to show how, as yet, a kind of civic incompetence reigns within the country, and how this situation has its roots in the belief, promoted by politicians themselves, that politics is an activity for experts only. The final outcome of his research took the form of a series of articles, in English, totalling 40 pages.
