![]() ![]() This is precisely a quantum operation, whose properties we now summarize. These include original papers, letters, broadly focused perspectives, comprehensive review articles, book reviews, and special topical issues. This method is based on a n-symbol obfuscation model and the matrix’s linear transformation, whose complexity dramatically decreases to. ![]() ![]() The memoryless in the section title carries the same meaning as in classical information theory: the output of a channel at a given time depends only upon the corresponding input and not any previous ones.Ĭonsider quantum channels that transmit only quantum information. Quantum Information Processing supports and inspires research by providing a comprehensive peer review process, and broadcasting high quality results in a range of formats. As a contrast to the standard classical zero-error coding, which has a computational complexity of, a general approach is proposed herein to find zero-error codewords in the case of quantum channel. We will assume for the moment that all state spaces of the systems considered, classical or quantum, are finite-dimensional. With this, the chapter discusses the depolarization channel and imprecise gates, as well as (briefly) amplitude and phase damping. 4.4 Classical and quantum channel capacities. ![]()
