This paper details an experimental and theoretical investigation into the electronic structure of the highly ionic, alkali oxide, potassium oxide (K 2O). The experiments were carried out using the relatively new technique ...
We find a regularized formula for the entanglement-assisted (EA) capacity region for quantum multiple access channels (QMAC). We illustrate the capacity region calculation with the example of the collective phase-flip ...
The scheme of entanglement-assisted quantum error-correcting (EAQEC) codes assumes that the ebits of the receiver are error free. In practical situations, errors on these ebits are unavoidable, which diminishes the ...
We investigate the construction of quantum low-density parity-check (LDPC) codes from classical quasi-cyclic (QC) LDPC codes with girth greater than or equal to 6. We have shown that the classical codes in the generalized ...
We show that two ways of manipulating quantum entanglement-namely, entanglement-assisted local transformation [D. Jonathan and M. B. Plenio, Phys. Rev. Lett. 83, 3566 (1999)] and multiple-copy transformation [S. Bandyopadhyay, ...
If entanglement is available, the error-correcting ability of quantum codes can be increased. We show how to optimize the minimum distance of an entanglement-assisted quantum error-correcting (EAQEC) code, obtained by ...

The modification of lifetime experienced by a fluorescent molecule placed in an arbitrary environment is investigated theoretically within the framework of linear response theory. We present a complete description of the ...
Miniature specimen testing to evaluate mechanical properties, presents a novel opportunity to undertake structural integrity assessments of in-service power generation components, by removing only a very small volume of ...
A scaling analysis of conductance for photons in two dimensions is carried out and, contrary to widely held belief, we find strong evidence of a mobility edge. Such behavior is compatible with the existence of an Anderson ...
Environmental scanning electron microscopy (ESEM) was used to perform electron beam induced deposition (EBID) using a WF(6) precursor. The deposits consist of WO(3) nanocrystals embedded in an amorphous matrix. Oxide ...
An exact theory for modelling modes of generalised defects in 2D photonic crystals (PCs) with a genuinely infinite
cladding is presented. The approach builds on our fictitious source superposition method for simple defects ...
We study the unsorted database search problem with items $N$ from the viewpoint of unitary discrimination. Instead of considering the famous $O(\sqrt{N})$ Grover's the bounded-error algorithm for the original problem, we ...
This article presents experimental investigation on the effect of layer displacements for an X-band circularly polarized patch antenna. Experimental results demonstrate that such antenna makes use of high-low-low dielectric ...

We present spatially resolved measurements of carrier density in two 1.3 mum distributed feedback laser diodes. By measuring the response of the spontaneous emission intensity to a 50 MHz drive current we can observe small ...
Double-cup assemblies of nanoscale gold semi-shells have been synthesized using a combination of thermal evaporation and chemical etching. The optical extinction of these structures peaked at 740 nm, but there was also ...
The formation of single-crystal diamond membranes is an important prerequisite for the fabrication of high-quality optical cavities in this material. Diamond membranes fabricated using lift-off processes involving the ...

In this paper, we present a facile method to synthesize SnO2 nanofibres. Unlike the conventional CVD process for synthesizing nanofibres, the present synthesis method needs neither specific source gas nor substrates. Sn?Ag ...
The density matrix divide-and-conquer technique for the solution of Kohn-Sham density functional theory has been implemented within the framework of the SIESTA methodology. Implementation details are provided where the ...
