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 ...

How to test the “quantumness” of a quantum computer? Miroslav Grajcar
... The looming impossibility to predict the behavior of any big enough quantum processor (adiabatic, gate-based, etc) and even to test it for “quantumness” using classical tools, is the elephant in the room, and it may effectively restrict any further progress. Even taking the optimistic view, that qua ...

A (very) brief tour of quantum mechanics, computation, and category
... the result will be exactly that computed value. Similarly, the particles’ positions may be observed, computed, and checked. However, the measurement operators corresponding to these observables (position and momentum) do not commute, and hence an exact knowledge of position entails some uncertainty ...
