0 On the generation and identification of optical Schrödinger cats

چکیده
We discuss the possibility of generating and detecting, by a tomographic reconstruction of the Wigner function, a macroscopic superposition of two coherent states. The superposition state is created using a conditioned measurement on the polarisation of a probe photon entangled to a coherent state. The entanglement is obtained using a Kerr cell inserted in a Mach-Zender interferometer. Some hint about generation of GHZ states is given as well.

Quantum simulation of decoherence in optical waveguide lattices.
We suggest that propagation of nonclassical light in lattices of optical waveguides can provide a laboratory tool to simulate quantum decoherence phenomena with high non-Markovian features. As examples, we study decoherence of optical Schrödinger cats in a lattice that mimics a dissipative quantum harmonic oscillator coupled to a quantum bath, showing fractional decoherence in the strong coupli...
متن کاملIdentification of Helicobacter spp. in gastrointestinal tract, pancreas and hepatobiliary system of stray cats
The aim of the present study was to determine the presence of Helicobacter species in different parts of gastrointestinal tract, hepatobiliary system and pancreas of stray cats. Six different sites at the level of genus, gastric (H. heilmannii and H. felis) and enterohepatic species of Helicobacter were investigated in six cats using species-specific primers by polymerase chain reaction (PCR). ...
متن کاملImpacts of Nanoparticles and Nano Rod Arrays on Optical Generation Rate in Plasmonic-Based Solar Cells
In this article, the effect of plasmonics properties of metal nanorods and nanoparticles on solar cell performance were investigated and simulated. Due to the classic solar cell disadvantages, it seems that a plasmonic solar cell is one of these methods. In plasmonic solar cells, because of plasmonic effect, a high electric field builds around metal nanoparticles so that high conversion efficie...
متن کاملMolecular identification and phylogenic analysis of Bartonella henselae isolated from Iranian cats based on gltA gene
One of the most important species of the Bartonella genus is B. henselae that causes a zoonotic infection, cat scratch disease (CSD). The main source of the bacteria is cat and the carrier is Ctenocephalides felis flea. One hundred and forty nail and saliva samples were collected from 70 domestic cats. Positive samples for B. henselae were characterized by po...
متن کاملAnalytical Soliton Solutions Modeling of Nonlinear Schrödinger Equation with the Dual Power Law Nonlinearity
Introduction In this study, we use a newly proposed method based on the software structure of the maple, called the Khaters method, and will be introducing exponential, hyperbolic, and trigonometric solutions for one of the Schrödinger equations, called the nonlinear Schrödinger equation with the dual power law nonlinearity. Given the widespread use of the Schrödinger equation in physics and e...
