We report experimental generation of a noisy entangled four-photon state that exhibits a separation between the secure key contents and distillable entanglement, a hallmark feature of the recently established quantum theory of private states. The privacy analysis, based on the full tomographic reconstruction of the prepared state, is utilized in a proof-of-principle key generation. The inferior...

Through high-harmonic generation, attosecond pulse train can be produced with half-cycle temporal separation. Each pulse in this train carries information on physical processes in the medium during its generating time. Here, the spatially chirped laser pulses are used in high-order harmonics generation experiment to get a train of isolated attosecond pulses angularly separated—an attosecond lig...

8 ABSTRACT: High-throughput, quantitative, and rapid microfluidic9 based separations has been a long-sought goal for applications in 10 proteomics, genomics, biomarker discovery, and clinical diagnostics. 11 Using droplet-interfaced microchip electrophoresis (MCE) techni12 ques, we have developed a novel parallel MCE platform, based on 13 the concept of combining the Slipchip principle with a n...

BACKGROUND The immunomagnetic separation technique is the basis of monocyte isolation and further generation of monocyte-derived dendritic cells. OBJECTIVE To compare the efficiency of monocyte positive and negative separation, concentration of beads, and their impact on generated dendritic cells. METHODS Monocytes were obtained using monoclonal antibody-coated magnetic beads followed the F...

Direct numerical simulation (DNS) is used to study the evolution of a boundary layer that was laminar initially followed by separation and then reattachment owing to generation of turbulence. This creates a closed region of recirculation, known as the laminar-separation bubble. The present simulation emulates the flow environment encountered in a modern LP turbine blade, where a laminar separat...

Given that the majority of communications devices are mobile terminals, efficient mobility support should be a key feature in the new generation network or future Internet. The current Internet does not have native mobility support. Although variants of Mobile IP protocols have been developed to address this problem, these protocols cause signaling overhead, create a single point of failure, an...

The proper solid waste recycling process starts at the houses with attendance of individuals. presented study includes comprehensive research on individuals’ shopping and generation behaviors, awareness management issues, readiness willingness for source separation, their self-evaluation self-annoyance about generation. current was conducted by administering a detailed questionnaire to 300 peop...

This paper discusses the mechanism of generation of free charges in organic photovoltaic cells (OPV) from electrostatically bound electron-hole pairs. The efficiency of this process is explained when interfacial charge-transfer (CT) states are generated by direct optical excitation. We used semiclassical quantum dynamics at short timescale (∼100 fs) and Redfield theory at relatively long timesc...

The dissociation of photogenerated excitons and the subsequent spatial separation of the charges are of crucial importance to the design of efficient donor-acceptor heterojunction solar cells. While huge progress has been made in understanding charge generation at all-organic junctions, the process in hybrid organic:inorganic systems has barely been addressed. Here, we explore the influence of ...
