Integrated multiresonator quantum memory

We develop the integrated efficient multiresonator quantum memory scheme based on a system of three interacting resonators coupled through a common resonator to an external waveguide via switchable coupler. It is shown that high-precision parameter matching based on the step-by-step optimization makes it possible to efficiently store the signal field and on demand retrieval the signal at specified time moments. Possible experimental implementations and practical applications of the proposed quantum memory scheme are discussed.Comment: 7 pages, 4 figure

NEM and MFEM Simulation of Interaction between Time-dependent Waves and Obstacles

Fundamental research challenge of structural integrity and construction resistance while interacting with fluid or gas is of high importance when estimating their efficiency and lifetime. The paper presents the simulation results of interaction between incompressible ideal fluid and an escarpment at the bottom, and interaction between viscous incompressible fluid and an obstacle above fluid surface. Flow patterns at different times and chronograms of hydrodynamic loads on solid walls of computational domain, horizontal and vertical obstacles are displayed
