Reconfigurable distribution of entangled states is essential for operation quantum networks connecting multiple devices such as memories and computers. We introduce new network architecture enabling control the state propagation direction using linear-optical phase shifters offering reconfigurable connections between nodes. The basic two-photon entanglement scheme first introduced to illustrate...

The multi-pass recirculating proton linac can significantly improve the usage efficiency of rf superconducting cavities by accelerating beam through same cavity multiple times. However, in order to achieve acceleration for different energy beams, longitudinal phase synchronous conditions among these beams have be satisfied. In this paper, we propose a fixed field shifter system based on two ben...

This paper presents a core chip design in SiGe Heterojunction Bipolar Transistor base for X-band phased array Transmit/Receive (T/R) module. Usually phase shifters for X-band application were done by using of GaAs technique. Some commercial GaAs products for this type of integrate circuits are considered. The structure of the Core Chip for Phased Array T/R Modules is presented. Methods for the ...

We developed a 4×4 fully non-blocking crossbar switch fabric based on interferometric thermal phase shifters, where heating is achieved using resistive elements around the silicon waveguide. We achieved switching times of 5 μs, with 41 mW power consumption in an individual switching element.

In this paper, we reviewed RF MEMS research efforts in planar structures and phased arrays. For planar transceivers, we have demonstrated several RF MEMS devices in order to establish building blocks in integrated millimeterwave systems. For phased-array applications, we have demonstrated two architectures for beam forming and steering without solid-state phase shifters.
