An Improved Quantum Algorithm for Searching an Ordered List
... Once we have found the gradient, we reduce the problem to a one-dimensional search along this vector to find a new C for which cost(C ) < cost(C). We perform this minimization by a process known as bracketing the minimum. Although this method is only useful for finding a local minimum along the line ...

Near-red emission from site-controlled pyramidal InGaN quantum dots
... We have fabricated InGaN nanostructures on top of GaN hexagonal pyramids by selective metalorganic vapor-phase epitaxy. With this approach, we are able to exactly control the position of the emitting quantum dot, which is an essential requirement for functionalized single-photon emitters. The emissi ...
