In the case of the hydrogen atom the effect of taking into account the lowest order quantum field theory correction is a splitting in the degenerate doublets of the solution to the Dirac equation: states with different orbital angular momentum coupling to the same value of j. At the second level the ...

Space-time description of squeezing

Our description of squeezed states may certainly be criticized as an exercise in elementary quantum field theory that does not lead to any progress in our understanding of the physics of these phenomena. To defend ourselves against such criticism, we would like to point out that the description of s ...

Non-linear gates enabling universal quantum computation
... In the above described endeavour, non-linear quantum systems are crucial. Given that, as said above, experimental research has recently seen impressive developments in terms of scalability, accessing to non-linearities would be the next big step. The reason is that non-linearities are necessary for ...

On coloring the rational quantum sphere
... Due to the density of points colored with any single color, any such coloring is non-continuous in the sense that between any two points of equal color there is a point (indeed, an infinity thereof) of different color. Let us then assume that any such value-definiteness might apply also to non-local ...
