The quadratic-phase Fourier transform (QPFT) has gained much popularity in recent years because of its applications image and signal processing. However, the QPFT is inadequate for localizing spectrum, which required some applications. In this paper, wave packet (QP-WPT) proposed to address problem, based on (WPT) QPFT. Firstly, we propose definition QP-WPT give relation with windowed (WFT). Se...

usually in the form of parallel processing with parallel multi-processor systems are designed .for this reason irregular flow may occur with packages. when you're tired and it all comes out in his np (network processors)  system, reset depending on network performance is negatively affected and we delayed to do this, the design of processors working in parallel packet transmission by avoid...

Quantum computers hold the promise for efficiently factoring large integers [1]. However, to do this beyond a most modest scale they will require quantum error correction [2]. The theory of quantum error correction is already well studied in two-level or spin2 systems (in terms of qubits or quantum bits) [2–7]. Some of these results have been generalized to higher-spin systems [8–11]. This work...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

Experimental and theoretical work is presented on the control o f wave packet dynamics in atomic and molecular systems. Using sequences of phase-locked optical pulses, the link between optical phase and quantum mechanical phase is explored in the Na atom and N aj dimer, representing a step towards the logical engineering of quantum states in more complicated systems. A novel apparatus, construc...

The phenomena of recurrence or revival is a beautiful combination of classical mechanics, wave mechanics, and quantum laws. A wave packet evolves over a short period of time in a potential, initially following classical mechanics. It spreads while moving along its classical trajectory, however rebuilds itself after a classical period. It follows wave mechanics in its long time evolution and gra...
