A novel, compact, and highly selective ultra-wideband (UWB) bandpass filter with a narrow notched band is presented. Apart from having a basic structure of a slotline multiple-mode resonator (MMR) and microstrip feed lines, this novel design introduces a cross-coupling between the input and output feed lines to enhance the filter selectivity. The design strictly follows the theory and verified by...
Recently Li et al. proposed special partially entangled states serving as quantum channel in quantum controlled teleportation, while there are some limitations in their scheme. Based on that, we present a possible improvement in this paper. We construct a novel three-particle partially entangled state which is suitable for perfect controlled teleportation. A simple quantum circuit is designed to obtain...
