Maximum speed of quantum gate operation
, 2003
"... We consider a quantum gate, driven by a general timedependent Hamiltonian, that complements the state of a qubit and then adds to it an arbitrary phase shift. It is shown that the minimum operation time of the), where h is Planck’s constant, E is the average over time of the quantummechanical aver ..."

Probabilistic Nonlocal Gate Operation Via Imperfect Entanglement
, 2002
"... Nonlocal gate operation is based on sharing an ancillary pair of qubits in perfect entanglement. When the ancillary pair is partially entangled, the efficiency of gate operation drops. Using general transformations, we devise probabilistic nonlocal gates, which perform the nonlocal operation conclu ..."

Contour and Texture Analysis for Image Segmentation
, 2001
"... This paper provides an algorithm for partitioning grayscale images into disjoint regions of coherent brightness and texture. Natural images contain both textured and untextured regions, so the cues of contour and texture differences are exploited simultaneously. Contours are treated in the interveni ..."

in the intervening contour framework, while texture is analyzed using textons. Each of these cues has a domain of applicability, so to facilitate cue combination we introduce a gating operator based on the texturedness of the neighborhood at a pixel. Having obtained a local measure of how likely two nearby pixels
A Study on Dynamic Water Quality Change for Gate Operation in
, 2013
"... The inflow from Daejeo gate and the outflow from Noksan gate in Seonakdong river, which is a reservoirlike river with the characteristics of stagnant water, is very important for TMDLs (Total Maximum Daily Load) of Nakbon N unit watershed. However, there are very few measured data for calculating b ..."

base flow. The operating data is much different from the actual measured data because the probable maximum flowrate is used for gate operation. In this study, the operating flowrate data of Daejeo and Noksan gates are compared with the monthly water quality data from Ministry of Environment monitoring
Temporal CaseBased Reasoning for Reservoir Spillway Gate Operation Recommendation
"... AbstractIn the traditional decision making process, in order to solve a problem, every possible solution will be generated and evaluated. The most optimum decision will be selected. However, this approach is unsuitable for urgent decision making, due to the time needed to evaluate all option. This ..."

to develop the gate operation decision support model, which covers reservoir spillway gate operation activities from year 1998 to 2004. This model was then tested, and yielded up to 89 percent decision accuracy.
FAST TRACK COMMUNICATION Electron dynamics in quantum gate operation

"... We model the evolving timedependent electronic structure of a solidstate quantum gate as it performs basic quantum operations. Our timedependent configurationinteraction method follows the evolution of two donor electron spin qubits interacting with a third, optically excited, control spin in an ..."

Elementary Gates for Quantum Computation
, 1995
"... We show that a set of gates that consists of all onebit quantum gates (U(2)) and the twobit exclusiveor gate (that maps Boolean values (x, y)to(x, x⊕y)) is universal in the sense that all unitary operations on arbitrarily many bits n (U(2 n)) can be expressed as compositions of these gates. We in ..."

We give an elementary introduction to the notion of quantum entanglement between distinguishable parties and review a recent proposal about solid state quantum computation with spinqubits in quantum dots. The indistinguishable character of the electrons whose spins realize the qubits gives rise to further entanglementlike quantum correlations. We summarize recent results concerning this type of quantum correlations of indistinguishable particles. 1
