Universal Optimal Cloning of Qubits and Quantum Registers
We review our recent work on the universal (i.e. input state independent) optimal quantum copying (cloning) of qubits. We present unitary transformations which describe the optimal cloning of a qubit, and we present the corresponding quantum logic network. We also present a network for an optimal quantum copying “machine” (transformation) which produces N +1 identical copies from the original q...
متن کاملOutlier Detection Using Extreme Learning Machines Based on Quantum Fuzzy C-Means
One of the most important concerns of a data miner is always to have accurate and error-free data. Data that does not contain human errors and whose records are full and contain correct data. In this paper, a new learning model based on an extreme learning machine neural network is proposed for outlier detection. The function of neural networks depends on various parameters such as the structur...

Title of dissertation: QUANTUM SWITCHING NETWORKS: UNICAST AND MULTICAST Manish Kumar Shukla Doctor of Philosophy, 2010 Dissertation directed by: Professor A. Y. Oruç Department of Electrical Engineering Quantum switching networks are analogs of classical switching networks in which classical switches are replaced by quantum switches. These networks are used to switch quantum data among a set o...
متن کاملCode-Copying in the Balochi Language of Sistan
This empirical study deals with language contact phenomena in Sistan. Code-copying is viewed as a strategy of linguistic behavior when a dominated language acquires new elements in lexicon, phonology, morphology, syntax, pragmatic organization, etc., which can be interpreted as copies of a dominating language. In this framework Persian is regarded as the model code which provides elements for b...
متن کاملA Graphic Representation of States for Quantum Copying Machines
Abstract: The aim of this paper is to introduce a new graphic representation of quantum states by means of a specific application: the analysis of two models of quantum copying machines. The graphic representation by diagrams of states offers a clear and detailed visualization of quantum information’s flow during the unitary evolution of not too complex systems. The diagrams of states are expon...
متن کاملImproving detectors using entangling quantum copiers
Copying machines in general use two approaches. One of the extreme cases is a classical copying machine, where measurements ~destructive or nondestructive! are made on the original state, the results of which are then fed as parameters into some state preparation scheme that attempts to construct a copy of the original. This approach obviously allows one to generate an arbitrary amount of copie...
