—The natural trajectory tracking problem is studied for generic quantum states represented by density operators. A control design based on the Hilbert-Schmidt distance as a Lyapunov function is considered. The control dynamics is redefined on an extended space where the LaSalle invariance principle can be correctly applied even for non-stationary target(More)
—A Lyapunov-based control design for natural trajectory-tracking problems is analyzed for quantum states where the analysis in the generic case is not applicable. Using dynamical systems tools we show almost global asymptotic stability for stationary target states subject to certain conditions on the Hamiltonians, and discuss effectiveness of the design(More)
The Long Term Evolution (LTE) system is the evolution of Universal Mobile Telecommunications System (UMTS). The LTE system is now increasingly being deployed throughout the world. Therefore, the security of the LTE system is more and more significant. In this paper, we present a method of interference the LTE system, called jammer interference. It exploits(More)
