چکیده
In this paper, the 2-state decomposed-type quantum walk (DQW) on a line is introduced as an extension of (QW). The time evolution DQW defined with two different matrices, one assigned to real component, and other imaginary component state. Unlike ordinary QWs, localization spreading phenomenon can coincide in DQWs. Additionally, always be converted corresponding 4-state QW identical probability measures. words, class QWs realized by DQWs 2 states. work, we reveal that there Grover walk. Then, derive weak limit theorem which regarded generalized walks.

On Hidden States in Quantum Random Walks
It was recently pointed out that identifiability of quantum random walks and hidden Markov processes underlie the same principles. This analogy immediately raises questions on the existence of hidden states also in quantum random walks and their relationship with earlier debates on hidden states in quantum mechanics. The overarching insight was that not only hidden Markov processes, but also qu...
متن کاملQuantum walks based on an interferometric analogy
There are presently two models for quantum walks on graphs. The “coined” walk uses discrete time steps, and contains, besides the particle making the walk, a second quantum system, the coin, that determines the direction in which the particle will move. The continuous walks operate with continuous time. Here a third model for quatum walks is proposed, which is based on an analogy to optical int...
متن کاملNovel Image Encryption based on Quantum Walks
Quantum computation has achieved a tremendous success during the last decades. In this paper, we investigate the potential application of a famous quantum computation model, i.e., quantum walks (QW) in image encryption. It is found that QW can serve as an excellent key generator thanks to its inherent nonlinear chaotic dynamic behavior. Furthermore, we construct a novel QW-based image encryptio...
متن کاملQuantum Walks, Quantum Gates, and Quantum Computers
The physics of quantum walks on graphs is formulated in Hamiltonian language, both for simple quantum walks and for composite walks, where extra discrete degrees of freedom live at each node of the graph. It is shown how to map between quantum walk Hamiltonians and Hamiltonians for qubit systems and quantum circuits; this is done for both a singleand multi-excitation coding, and for more genera...
متن کاملQuantum walks and quantum computation
The field of quantum information applies the concepts of quantum physics to problems in computer science, and shows great potential for allowing efficient computation. In this thesis I concentrate on a particular quantum information theoretic tool known as the quantum walk. There are two widely studied versions of the quantum walk, the continuous time walk, and the discrete time walk. The discr...
