We propose a simple scheme for the quantum teleportation of both bipartite and multipartite entangled coherent states with the success probability 1/2. The scheme is based only on linear optical devices such as beam splitters and phase shifters, and two-mode photon number measurements. The quantum channels described by the multipartite maximally entangled coherent states, are readily made by th...

A principle and design procedure of differential phase shifters and baluns with a specified bandwidth is given. Phase shifters and baluns proposed here comprise of two transmission lines(TL), one is conventional while the other is CRLH-TL. The operating frequency is properly chosen as to obtain a maximum bandwidth. The bandwidth is related to number of unit cells comprising CRLH-TL.A Wilkinson ...

An optical phased array of nanoantenna fabricated in a CMOS compatible silicon photonics process is presented. The optical phased array is fed by low loss silicon waveguides with integrated ohmic thermo-optic phase shifters capable of 2π phase shift with ∼ 15 mW of applied electrical power. By controlling the electrical power to the individual integrated phase shifters fixed wavelength steering...

This paper presents the design, development and experimental characterization of a monolithic phased array antenna integrated on a microwave laminate. A four-element linear antenna array is realized by cofabricating the corporate feed network, microstrip-CPW transitions, DC blocks, and mesoscale phase shifters on the same substrate. The phase shifters used here are electrostatically actuated an...

We have recently shown that the optimal power flow (OPF) problem with a quadratic cost function can be solved in polynomial time for a large class of power networks, including IEEE benchmark systems, due to their physical properties. In this work, our previous zero-duality-gap result is extended to OPF with arbitrary convex cost functions, and then it is proved that adding phase shifters to the...

Approved for public release; distribution is unlimited. Abstract: An ultra low power 180-degree , 1-bit phase shifter has been designed using Agilent's Advanced Design Software (ADS) co-simulation. Silicon-on-Insulator (SOI). MOSFETs were used as the switching elements because of their low current draw and low capacitance. A 1-bit 0, 180-degree phase shift has been realized with only two MOSFET...
