We provide a feasible necessary and sufficient condition for when an unknown quantum operation (quantum device) secretly selected from a set of known quantum operations can be identified perfectly within a finite number ...
We study the possibility of performing perfect teleportation of unknown quantum states from multiple senders to a single receiver with a previously shared stabilizer state. In the model we considered, the utilized stabilizer ...
The performance optimization of microwave low pass and bandpass filters using photonic band gap (PBG) structures was discussed. The low pass filters used periodic defective ground structures while bandpass filter used a ...
Large-area arrays of dispersed multilayer gold-dielectric nanocups were fabricated by colloidal lithography and studied by extinction spectroscopy. Hybridization of the elemental plasmons of the individual nanocups gave ...
Gold nanoparticles manifest one or more plasmon resonances, resulting in enhanced absorption and scattering of light at the resonant frequencies. The absorbed light is converted to heat. Here we analyze how the resulting ...
This paper investigates the performance of a prototype resistive fault current limiter (FCL) made using a high temperature superconductor (HTS). Its behavior under normal operation and short-circuit conditions in a 6 kV/1 ...

This chapter presents a systematic exposition of predicate transformer semantics for quantum programs. It is divided into two parts: The first part reviews the state transformer (forward) semantics of quantum programs ...
We use ab initio calculations of the tunneling current through a 1,4-phenylenedimethanethiol (XYL) molecule adsorbed between Au(1 1 1) electrodes to show that there are circumstances under which tunneling currents can be ...
In this study we present the effects of iron oxide (Fe2O 3) on titanium dioxide (TiO2) in synthesising visible-light reactive photocatalysts. A Fe2O3-TiO 2 composite photocatalyst was synthesized from Fe2(SO 4)3 and Ti(SO4)2 ...
High temperature superconductor (HTS) high levitation force density with passive and self-stabilizing features allows a number of special applications to be developed. Linear motor driving systems are commonly required for ...
We consider using a secret key and a noisy quantum channel to generate noiseless public communication and noiseless private communication. The optimal protocol for this setting is the publicly-enhanced private father ...
Recently, quantum adiabatic computation has attracted more and more attention in the literature. It is a novel quantum computation model based on adiabatic approximation, and the analysis of a quantum adiabatic algorithm ...
Measurement based quantum computation, which requires only single particle measurements on a universal resource state to achieve the full power of quantum computing, has been recognized as one of the most promising models ...
We present detailed experimental and numerical studies of random lasing in weakly scattering systems. The interference of scattered light, which is weak in the passive systems, is greatly enhanced in the presence of high ...
We show that in some cases, catalyst-assisted entanglement transformation cannot be implemented by multiple-copy transformation for pure states. This fact, together with the result we obtained in R. Y. Duan, Y. Feng, X. ...
Alternative materials are required to enhance the efficacy of plasmonic devices. We discuss the optical properties of a number of alloys, doped metals, intermetallics, silicides, metallic glasses and high pressure materials. ...
Ordinary Portland-cement clinkers were characterised using neutron and synchrotron powder diffraction. Rietveld analysis was performed using individual as well as combined data. Comparisons were made between phase ...
