Time correlations in atmospheric quantum channels

Efficient transfer of quantum information between remote parties is a crucial challenge for quantum communication over atmospheric channels. Random fluctuations of the channel transmittance are a major disturbing factor for its practical implementation. We study correlations between channel transmittances at different moments of time and focus on two transmission protocols. The first is related to the robustness of both discrete- and continuous-variable entanglement between time-separated light pulses, showing a possibility to enlarge the effective dimension of the Hilbert space. The second addresses a preselection of high-transmittance events by testing them with bright classical pulses followed by quantum light. Our results show a high capacity of the time-coherence resource for encoding and transferring quantum states of light in atmospheric channels.Comment: 11 pages, 6 figures, ancillary files include Python3 code and simulated dat

Writer Identification for chinese handwriting

Abstract Chinese handwriting identification has become a hot research in pattern recognition and image processing. In this paper, we present overview of relevant papers from the previous related studies until to the recent publications regarding to the Chinese Handwriting Identification. The strength, weaknesses, accurateness and comparison of well known approaches are reviewed, summarized and documented. This paper provides broad spectrum of pattern recognition technology in assisting writer identification tasks, which are at the forefront of forensic and biometrics based on identification application

Energy-Flow – A New Perspective on James MacGregor Burns’ Transforming Leadership: A New Pursuit of Happiness

This theoretical dissertation documents a personal transforming leadership experience; during which, I explored my Leadership as Energy-Flow model by having a virtual dialogue with the polymathic works of theorists and thinkers to corroborate and refine it. The model consists of a theory and a conceptual scheme. The energy-flow theory, based on the laws of physics and Chinese philosophy and cosmological science, fashions the energy-flow conceptual scheme. Using the conceptual scheme, I delve into the Premise of the Dialogue, “In what ways and to what extent would using the energy-flow frame of reference describe and stimulate new meanings in Transforming Leadership: A New Pursuit of Happiness?” I venture forth in this exploration, sparked by Bertrand Russell’s (1938) and James MacGregor Burns’ (1979) on leadership power, to discover how one might use energy-flow abstractions to represent leadership phenomena. Energy-flow abstractions are images of events captured in thought, within which one unfolds and enfolds new meanings and deepens understanding of transforming leadership. The dialogue with six different traditions includes the works of: Alfred North Whitehead on philosophy and science, Ilya Prigogine on physics, Abraham H. Maslow on human potentials, need hierarchy, and management, Mihaly Csikszentmihalyi on psychological energy-flow, Richard Gerber on physiological energy-flow and vibrational medicine, and Ralph H.G. Siu on quantum and the Tao of science of leadership. The dialogue then continues into the work of Burns (2003). Many of my epiphanies, using the energy-flow conceptual scheme to fathom transforming leadership theory, induce some propitious ideas for further exploration in viewing leadership as energy-flow and using energy-flow as a basis for deciphering human affairs.
