Continuous-variable quantum non-demolishing interaction at a distance
A feasible setup of continuous-variable (CV) quantum non-demolishing (QND)
interaction at a distance is proposed. If two distant experimentalists are able
to locally perform identical QND interactions then the proposed realization
requires only a single quantum channel and classical communication between
them. A possible implementation of the proposed setup in recent quantum optical
laboratories is discussed and an influence of Gaussian noise in the quantum
channel on a quality of the implementation is analyzed. An efficient
realization of the QND interaction at a distance can be a basic step to
possible distributed quantum CV experiments between the distant laboratories.Comment: 5 pages, 2 figure
Synthesis of Electromagnetic Metasurfaces: Principles and Illustrations
The paper presents partial overview of the mathematical synthesis and the
physical realization of metasurfaces, and related illustrative examples. The
synthesis consists in determining the exact tensorial surface susceptibility
functions of the metasurface, based on generalized sheet transition conditions,
while the realization deals with both metallic and dielectric scattering
particle structures. The examples demonstrate the capabilities of the synthesis
and realization techniques, thereby showing the plethora of possible
metasurface field transmission and subsequent applications. The first example
is the design of two diffraction engineering birefringent metasurfaces
performing polarization beam splitting and orbital angular momentum
multiplexing, respectively. Next, we discuss the concept of the "transistor"
metasurface, which is an electromagnetic linear switch based on destructive
interferences. Then, we introduce a non-reciprocal non-gyrotropic metasurface
using a pick-up circuit radiator (PCR) architecture. Finally, the
implementation of all-dielectric metasurfaces for spatial dispersion
engineering is discussed
