PURPOSE Zirconia is a good candidate material in the dental field. In this study, we evaluated biological responses against a zirconia drill using a bone cavity healing model. MATERIALS AND METHODS Zirconia drills, stainless steel drills, and the drilled bone surface were observed by scanning electron microscopy (SEM), before and after cavity preparation. For the bone cavity healing model, th...

We show how the state of an atom trapped in a cavity can be teleported to an atom trapped in a distant cavity simply by detecting photon decays from the cavities. This is a rare example of a decay mechanism being made to play a constructive role in quantum information processing. The scheme is comparatively easy to implement, requiring the minimal technology of being able to trap a single three...

F. O. Prado, N. G. de Almeida, M. H. Y. Moussa and C. J. Villas-Bôas Universidade Federal de São Carlos, São Carlos, Brazil and Universidade Católica de Goiás, Goiânia, Brazil Abstract In this work we show how to engineer bilinear and quadratic Hamiltonians in cavity quantum electrodynamics (QED) through the interaction of a single driven two-level atom with cavity modes. The validity of the en...

Materials and Methods: The study was conducted on 30 children in the age group of 8-15yrs, each having at least three permanent molar teeth with non-pulpally involved carious lesions. Each of the three teeth was randomly assigned to be treated with either Carie-care, Carisolv or high-speed cavity excavation with air-rotor. The following assessments were made for each tooth: efficacy of caries r...

We report nonclassical correlations in the light transmitted by a collection of two-level atoms strongly coupled to a single mode of the electromagnetic field of a driven optical cavity. This cavity QED system can produce bunched light that violates the Schwarz inequality due to the state preparation of the system from the detection of a photon. The correlation function shows oscillations at a ...

We propose a realistic protocol for the preparation and readout of mechanical Bell states in an optomechanical system. The proposal relies on parameters characterizing a photonic crystal cavity mode, coupled to two localized flexural modes of the structure, but equally applies to other optomechanical systems in the same parameter range. The nonclassical states are heralded via optical postselec...

Our research involves application of methods well-studied in virtual multiagent systems (MAS) but less well-understood in physical multi-robot systems (MRS). This paper investigates the relationship between performance results collected in parallel simulated (multiagent) and physical (multi-robot) environments. Our hypothesis is that some performance metrics established in simulation will predi...
